Automatic switching on of low beams, how to make automatic switching of low beams with your own hands. Automatically turning on low beam headlights: how to do it yourself Automatically turning on low beam headlights with your own hands

Good evening to all Toyota drivers!

Today I tried out the method of turning on the low beam headlights when the car was moving, which I mentioned on the caribovod forum in one of the topics. This feature is relevant due to the new rules according to which you must always travel with your neighbor(!), unless, of course, you have daytime running lights provided by design. And as you know, almost no old cars have such lights :)

In this scheme, the light automatically turns on only when the ignition is on, as soon as you remove the selector from parking gear [P] (models with automatic transmission or remove it from the handbrake (models with manual transmission) or engage gear [D] (this option is for those who has a corresponding light [D] on the instrument panel, indicating that this gear is engaged).
The topic is interesting. Question: what is the best way to connect to the standard wiring, cut in and twist it, or is there something more interesting?
I myself tested the scheme on my AE95 Carib with automatic transmission - I will describe it in detail. For manual transmission and other Toyota models, nothing should change radically; appropriate amendments will be given in the text. The connection diagram is very simple, so you don’t have to be a whiz at electrical engineering to implement it - anyone can do it, if only they had the desire and the time for at least a couple of hours.

So, let's begin!

First, the theory (informative:).

Schematic diagram of the device (two different diagrams are given, explanation below):

The first is intended only for those who have a gear light [D] on the instrument panel, usually these are models from 91-92 with automatic transmission.
The second is for everyone else. Only if you have a manual transmission, instead of outputting to the parking gear engagement sensor (P- in the diagram), you will need to connect to the sensor hand brake.

Persons acting in the diagram:
D+ - positive terminal of the light bulb [D] in the panel, indicating that gear [D] is engaged.
EL and “ground” - taken from the connector of the steering column headlight switch
H - turn on the headlights from there
IG+ - “ignition” output from the ignition switch connector (provides 12 V when the key is in the ON position)
P- - output from the parking gear engagement sensor [P].

With the first one, everything is simple, if the [D] light comes on (let's go!), the relay is activated and closes the headlight switch contact of the steering column switch - the headlights are on!

The second one is more difficult, because The parking sensor is closed in the [P] position and open in other positions. Therefore, the second relay uses normally closed contact 87a to turn on the headlights. Why is the first relay needed? In order not to drain the battery! Because if you leave only one second relay and use constant 12 V instead of IG+, then the relay will always work when the car is stationary, which will someday lead to the battery being drained. Therefore, we will turn on our circuit only when the ignition is turned on - 12 V will be supplied to IG+, the first relay will close and “drag” the EL contact of the steering column switch to the second relay. The second relay will work and will not allow the headlights to turn on.

As soon as the automatic transmission selector is moved to a position other than P (or the manual transmission is removed from the handbrake), the second relay will stop working and close contacts EL and H and the headlights will turn on! By the way, it is not necessary to put the manual transmission on the handbrake in the parking lot (relevant in winter!), because... the circuit will not work when the ignition is turned off.

We've sorted out the theory, now let's move on to practice!

We will need the following parts and tools:
1. Standard automotive relays with connectors (one or two - see theory:)

Hint: if anyone has parts left after installing the alarm, there are probably a couple of relays and connectors lying around :) I got mine from there.

2. The wire is about a meter long. There are usually wires in the connectors to the relays, but they are short.
3. Electrical tape, double-sided tape is also possible, but not necessary.
4. Screwdrivers, pliers, wire cutters (as a last resort, scissors).
5. It is advisable to have a tester (also known as a multimeter and a tester). Check once, cut once is our motto!
6. Reserve time for at least a couple of hours or more (depending on your experience in these matters, as well as your ability to disassemble the carib :).

Have you collected everything? Then go ahead and disassemble the car!

Unscrew the bottom cover under the steering wheel at the points indicated by the arrows:

We plug the wires into the relay connectors according to the diagram suggested above:

We connect the EL (ground) and H terminals from our relays to the terminals of the steering column switch connector. The connector itself is like this for Carib 95 bodies:

You may have a different one, and accordingly, the contacts may be located in a different place, look for yourself using the ABC book or at random using a tester.

We connect our wires with relays to these contacts (white crap - I already wrapped the electrical tape):

Unfortunately, in my photo everything is already secured with electrical tape, but I schematically marked the connections there with a dotted line. The idea is to connect the EL (ground) pin from our circuit to the white wire, and the H to the red wire. The colors may, of course, differ, but they will certainly be the same.

If yours is different, look in the primer or again with a tester :)

Everything is ready under the steering wheel, we move the P- wire deeper and further away, attach the relays somewhere nearby, and put the connector of the steering column switch in place:

The following is relevant only for automatic transmissions and a circuit with two relays:

Now, we unscrew the plastic decoration around the selector, along with it we will also have to unscrew the plastic on which the buttons, handbrake and armrest are located, otherwise we will not get to the inside of the selector.

Our wiring, run deep, can now be pushed through to the selector (in the picture above it is already routed :). Now, you need to connect it to the negative terminal of the parking gear sensor, but not to ground! Determining which of them is the mass if there is no tester can be very simple: open the sensor connector, switch to N. Since our circuit is almost ready and should, in theory, already work, you can turn on the ignition and the headlights should light up on their own. If this does not happen, then something from the above was done wrong. If the headlights come on, then with neutral and the ignition on, you should try to connect our wiring first to one of the contacts of the open connector, then to the other. If, when connected to one of the contacts, the headlights go out, then this contact is the “ground”, which means that our wiring must be connected to another contact of the same connector :)

If you have a manual transmission, you can, as in the previous case, run the wire there, but connect to the sensor parking brake. Or, disassemble the instrument panel and connect this wire to the negative terminal of the parking brake indicator.

If you are connecting a circuit with one relay (100th body with automatic transmission), you need to disassemble the instrument panel and feel for the + near the [D] light bulb (you can brute force until it works) and connect the D+ terminal from the relay to it.

Now we put everything back together in reverse order and are glad that we don’t have to remember to turn on the low beam during the day, that the clock doesn’t dim, the lights don’t light up during the day, and the panel doesn’t light up when it’s already light :)

I would be glad if the information provided was useful to someone! Thank you for your attention.

The topic is interesting. I have a Kaldina, I want to do something similar on it. Question: what is the best way to connect to the standard wiring, cut the insulation and twist it, or is there something more reliable?

Each of us dreams that own house was automated and to turn on the light or TV you just had to enter the room. If things are not going well with household appliances in terms of automation, then with the lighting system everything is much better. And today, in a house or apartment, it is relatively easy to create a system for automatic lighting using special devices.

Our article will tell you how you can organize with your own hands a high-quality lighting system that operates automatically in any room of the house.

Backlight automation: advantages and purpose

Creating a system for automatic control lighting in home spaces is a dream that can easily be realized today with the help of special equipment. Such systems in the house have the following advantages:

• efficient and comfortable control of lighting fixtures without direct human intervention;
• possibility to install automatic device DIY light control systems;
• automatic switching on of lights at night;
• saving on electricity. The device (motion sensor, relay, etc.) that is used in a given situation allows you to achieve varying degrees of energy savings.

Automatic room lighting

It is worth noting that automatic lighting systems used indoors are included in the concept of “smart home” or “smart light”. By connecting such systems, you get the opportunity to quickly, comfortably and effectively control the level of lighting in any room of the house where the necessary equipment is installed.
Depending on what device a particular device has (sensor, relay, etc.), turning on the light can be done as follows:

• through registration by the device in a given area of ​​movement. Here the device contains a special sensor that detects any changes in the controlled area. Here, to turn the lighting off/on, you need to install a motion sensor;
• through sound effects. For example, to turn on the light you need to clap your palms. Here you need a special sound switch;
• through the degree of illumination. In this situation, a relay is used, the device of which is capable of assessing the level of illumination in the house and, when it falls below a certain indicator, turning on the light.

Note! All of the above methods of turning on and off lighting at night can be used both indoors and outdoors. But those devices that are capable of responding to an audio signal should be installed indoors to reduce the risk of false alarms.

In some situations, you can even combine devices that have different device to achieve the most complete automation of the automatic light switching system in any room of the house or apartment.
Now let's look in more detail at each type of device used to organize an automatic lighting system.

Motion sensors are the most common option

Most often, an automatic lighting system in a house is organized by installing motion sensors. Such devices come in a wide variety:

• infrared. They are the safest in terms of long-term use in residential areas. They evaluate changes in the thermal signal and, if they detect a difference between the sent and received signal, they can turn the lights in the room on or off;

Infrared motion sensor

• microwave and ultrasonic sensor. Such products are often used to automate outdoor lighting systems. This is because microwave light control, especially when used for a long time, can have a negative impact on people's health. The operating principle of microwave and ultrasonic sensors is almost the same. The only difference is the type of signal received and emitted: microwaves or ultrasound. The organization schemes of such devices are almost identical;

Microwave motion sensor

Combined sensor

• combined sensor. This type of light control, like infrared, is the most optimal for the home. The combined sensor device contains two types of sensors that analyze signals in the monitored area.

Note! Combined and infrared sensors give a minimum number of false alarms.

For proper operation of the device, connection diagrams are needed, which are usually provided by manufacturers and are either in the instructions for the device or printed on the side of the package. Connection diagrams may have different type. It all depends on the model of the device with which you plan to control the light.
Installation of motion sensors is possible in any room of the house, including the bathroom and toilet. The light in such a situation will turn on when a person enters the room, and turn off when he leaves.
In addition, such devices are often combined with such an element as circuit breaker Sveta. It can complement other types of devices in this system.

Smart switch - clap your hands

Smart switch

Another rather original, but nevertheless popular way to turn on the light in a room is to install a switch that responds to hand clapping.

This device is equipped with a microphone, which is characterized by high selectivity. This microphone is able to distinguish a specific sound and separate it from other sound vibrations. In addition, the smart switch is equipped with special automation that is capable of analyzing the received sound spectrum and isolating the necessary signal from it.

Note! A smart switch can respond not only to the clap of your palms, but also to a special word. If desired, any variation of sound vibrations can be used as a signal. The main thing here is to set everything up correctly.

To install such a switch, special circuits are also used. This must be taken into account when installing the device in the house.
It is best to use the switch in rooms such as a bedroom, living room, kitchen, hallway. But a smart switch is not suitable for a bathroom with a toilet.

Photo relays and their role in the automatic home lighting system

Photo relay

All devices that are used for organization in the home automatic system backlights can, to some extent, respond to the degree of illumination. But there are special products that respond to the level of natural light. These are relays of different modifications.

Light control here occurs when the level of natural light decreases below a set value. In order for the control to be correct, a relay of this type must be installed using correct schemes. The relay is installed in the lighting fixture. Only after this control will be available. Therefore, if even one wire is connected incorrectly, the relay will not function as intended.

Photo relay connection diagram

At the same time, it is worth noting that when organizing an automatic lighting system inside a residential building, photo relays or other modifications are rarely used. More often they are included in the external lighting system, where their placement will be most relevant and effective. Here, as a rule, a photo relay is used, which looks like a sensor. It has a certain sensitivity to light rays. When the sun's rays hit the relay, it causes the device to switch to insulator mode. But in the dark, when the light flux weakens, the relay is converted into a conductor. As a result of this transformation, the lights turn on at night and in the evening. The device is powered from the house electrical network.

Conclusion

In order to organize high-quality and effective system automatically turn on the light, you can use three groups of devices. Each of them has its own advantages and disadvantages, which should be taken into account when choosing for your home. There are some devices (microwave motion sensors), the long-term operation of which near people is unacceptable due to significant harm to health. And this article will help you make an informed choice in favor of one or another type of automatic device for lighting living rooms.

How to select and install volume sensors for automatic light control

Automatic switching on of headlights is necessary to turn on the headlights in the event of a sharp deterioration in visibility without driver intervention. In some countries, it is necessary to turn on the headlights when the vehicle is moving.

On foreign cars, automatic headlight switching is installed, for which a corresponding sensor is used. Often this sensor is combined with a rain sensor attached to Windshield. The principle of this sensor is based on measuring illumination using photocells.

But this method is unlikely to be suitable for a domestic car owner. According to the rules traffic Low beam headlights must be turned on not only at night, but also during the day. When this requirement arose, there was a need to automatically turn on the headlights when the car is moving and turn them off when parking, for economical use of energy and to prevent leaving the headlights on when parked. According to the laws of the market, electrical equipment companies for automobiles and craftsmen immediately responded to this need. The principle of operation is different for all, depending on what the car owner wants to get and what costs and complications of the scheme he wants to go to. Let's look at some of the most common schemes.

A way to turn on for the forgetful.

The most simple circuit Automatic headlight switching on protects against driver forgetfulness and prevents headlights from turning on when the ignition is off. On most cars this is done during design at the manufacturer, and where it is not implemented it can be easily done. To do this, simply supply power to the power button or headlight relay through the ignition switch terminals, which are closed when the ignition is turned on, but open when the starter is turned on.

This method has a very important advantage: simplicity. There is an opinion that turning on the headlights will cause additional load, but this is not the case. If the connection is made correctly, then when the starter is turned on, the headlights will turn off. Conclusion: a simple, reliable method that does not require costs.

Automatic switching on of headlights via relay.

The second way to implement automatic headlight switching is to connect the electromagnet of the headlight switch relay or an additional relay to the generator excitation circuit, or rather the charging signal lamp circuit. This method is suitable for almost all modern cars.

To implement it, you need to add a five-pin relay of type 90.3747. Connect the wire from the ignition switch to pins 85 and 30. Connect pin 86 to the generator terminal to which the wire from the charge control lamp is connected. Connect pin 88 to the headlight relay or directly to the fuses protecting the headlight circuit.

In this case, when the ignition is turned on, the power from the ignition switch, the relay electromagnet coil, goes to negative through the generator winding, and the relay is activated and opens contacts 30 and 88. After the engine starts and the generator starts operating, a plus appears at the output of the generator warning lamp. The relay turns off and closes contacts 30 and 88, turning on the headlights.

To prevent a harmful circuit in this case, it is advisable to use a diode connected in series with the relay coil directed towards the generator. In this case, the headlights will light only if there is charging current, subject to the integrity of the circuit, which can be monitored by the battery charge lamp.

Automatic switching on of headlights via a pressure sensor.

In the third connection method, automatic turning on of headlights, Kulibins suggest using an emergency engine oil pressure sensor. The connection diagram is identical to that described earlier, only the relay coil is connected not to the generator, but to the emergency oil pressure sensor. In this case, the headlights will light up immediately after pressure appears in the lubrication system. The disadvantage is that the headlights turn on regardless of the serviceability of the generator. When the oil pressure is low idle speed, if the engine condition is not the best, the headlights will start flashing when the sensor is triggered.

Only the simplest and possibly primitive ways of implementing automatic headlight switching are discussed here. On the Internet you can find many more schemes, both simple and quite complex. Also in stores they can offer you ready-made blocks to implement this function.

In accordance with the changes made to the rules, low beams must be turned on while the car is moving on the road. Moreover, this decree applies to trips made both at night and during the day. Traffic police officers issue fines to violators, although the amount is small, but for law-abiding Even the fact of violating traffic rules is unpleasant for drivers.

turning on the low beam, how automation makes life easier for the driver

The problem with turning on the low beams before driving is usually that drivers simply forget to turn them on. To prevent violation of the rules, they have to leave the lights on when leaving the car, as a result one day they may discover that the battery is completely discharged.

Cars manufactured abroad, for the most part, are initially equipped with the device automatic turning on the headlights when predetermined conditions occur, the so-called. "Scandinavian" or "European" light. Most often, such devices are configured to trigger a rain sensor or photocell, controlling illumination level.

But for motorists who live on the territory of the Russian Federation, such functions are not enough, because driving with headlights on is required regardless of the time of day, light intensity or weather conditions.

In connection with this, there was a need to adjust and refine the systems power supply on cars manufactured in Russia, as well as on foreign cars with experience.

If we talk about the conveniences that are created by installing systems automatic switching on the low beam, they are as follows:

• unconditional switching on of lighting devices if a trip starts without driver participation
• turning off the headlights when the car stops moving
• getting savings on energy consumption
• additional conveniences are created if it is necessary to travel through a tunnel - there is no need to turn on the lights manually, the first seconds of the trip will be carried out with the low beam headlights already on, the path for the car will be sufficiently illuminated

Automatic switching on of low beam headlights when starting the car

As you know, demand for any product is an ideal incentive for its development and production. By issuing blocks automatic manufacturing enterprises willingly took up the task of switching on the low beam electrical equipment for cars.

The competitors are very successfully craftsmen who have created many interesting versions of homemade devices, distinguished by their varied functionality and complexity of designs.

With the help of very simple homemade circuits, you can achieve the desired result - the headlights will be connected synchronously with the ignition or engine start, during daylight hours only the light will turn on, and in the dark the side lights will also be on.

Scheme automatic turning on the headlights when starting the car

It is possible to ensure timely switching on of the light when connected to the ignition power source. But it should be remembered that some devices can be connected to the ignition switch located in any position, the functions of others will be activated only if the ignition is already turned on.

The most rational scheme is considered to be one through which power will be supplied to the relay (button) when the ignition switch contacts are closed. Turning off the engine when stopping will open the circuit, therefore turning off the headlights.

According to some drivers, such a design can cause an increase in load on the electrical circuit, but in fact, provided that each of the components of the structure is correctly connected, increased loads will not be observed.

What spare parts are needed to assemble the circuit? automatic inclusion

To arrange the system automatic to turn on the lighting fixtures you will need to find:

• standard five-pin relays
• wires
• diodes

To implement a more rational scheme with the option of connecting to a handbrake or oil pressure sensor, you will need to purchase:

• transistors, 2 pcs.
• wires
• relay
• microcircuit marked K561TP1

Description of work when assembling the circuit automatic turning on the low beam headlights

Experts consider the optimal solution to be the use of the stove switch off button, located on the right side of the switch block.

The work will be as follows. First you will need to dismantle the size switch, its location is the leftmost switch block.

Next, you will need to disconnect the positive wire and the key block, through which the switching off and switching on of the low beam is organized. Usually the connection is made using a double green wire; after disconnecting, this wire is connected to the relay.

You will need to cut an additional wire into the positive wire going to the heater switch and also connect it to the relay.

Then connect the wire to the relay that supplies power to the low beam headlights. Do not forget about the need to throw wires onto the body.

All formed connections will need to be carefully soldered, but if this is not possible, then you can limit yourself to using insulated twists

If the work is done well, we will get a Euro light system when the ignition is turned on.

But according to experts, this very simple option cannot be considered the most economical. In particular, this applies to winter time, when it will take some time to warm up the car. Also inappropriate The low beam will be turned on if repair work is necessary.

Scheme two

The above problems can be prevented by somewhat complicating the circuits. The additions made will make it possible to turn off the light at the moment of stopping, regardless of whether the ignition is turned on.

To obtain improved The circuit can be applied in two ways, connect to:

• handbrake
• oil pressure sensor

To connect via an oil pressure sensor, it is necessary to purchase 2 transistors, a relay and a microcircuit marked K561TP1. The parts can be placed in the housing from the relay, then the device is connected to the oil pressure sensor.

Turning on the engine will normalize the pressure in the lubrication system, the sensor contacts will open, and power will be supplied to the capacitor. The transistors included in the circuit will supply voltage to the relay, which will turn on the lighting fixtures.

Turning off the engine will cause power from the sensor to be transferred to the light bulb located on the dashboard. In this case, the capacitor included in the headlight control unit will begin to discharge, and power will not be supplied to the relay.

It should be noted that this scheme has some disadvantages, in particular - a decrease in oil pressure in the system will trigger the sensor (when coasting or idling), as a result of which the emitted light will blink.

A parallel connection will allow you to create a circuit that allows for both automatic and manual control.

You can regulate the on-off process by selecting appropriate resistance on the board. A higher resistance value means it will take longer for the lighting fixture to change status.

Not everyone approves of this method, because... The circuit is quite complex; additional wiring will be required and high-quality connections will be made.

We connect the circuit for switching on the low beam headlights to the handbrake

Connecting to the handbrake is not at all difficult; modifying the circuit will require adding another relay and a wire about a quarter of a meter long directly to the handbrake button contact.

This option will allow you to turn off the headlights when you start moving the handbrake, but when you release the handbrake, the headlights will light up.

Advantages and disadvantages of the assembled circuit

Homemade options undoubtedly There is advantages. They allow get required result And rid from claims employees traffic police By about Not included headlights in time movement car.

At this:

• price homemade systems enough low
• on manufacturing her Not required a lot of time

How to create an inexpensive circuit for automatic low beam headlights:

Certainly, do work their hands qualitatively will be able drivers, which It has Although—would initial preparation By electrical engineering And experience execution similar sort of works their hands.

Performance work By installation their hands will require from car owner maximum attentiveness And neatness. IN process operation should exclude opportunity hits moisture And mechanical deforming loads on fragments systems. IN systems electrical equipment cars Not recommended use gas-discharge lamps.

Lighting equipment, that is, headlights, plays a vital role in the operation process vehicle. With the help of optics, you can not only illuminate the road surface at night. Headlights also serve as an identification sign for other road users when visibility is poor.

If a driver drives with his headlights on, oncoming cars at a sufficiently large distance will be able to notice this. This allows accidents, erroneous maneuvers and other unpleasant situations on the roads.

According to traffic regulations, drivers are required to turn on low beams not only in the evening and at night, but also during the day. If the headlights do not work, this will be a strong argument for issuing a fine to the motorist.

Threats of a fine, as well as the issue of real safety, force drivers to look for convenient solutions to automate the process of turning on and off the low beam. There are several implementation methods, each of which has its own nuances, strengths and weaknesses.

The car owner has the right to choose how to automatically turn on the low beam headlights with his own hands.

Automation options

It is quite possible to install an automatic switch and switch that will be responsible for the low beam with your own hands. But first you need to decide which method of implementing the scheme suits you best than the others.

There are 3 current options available:

• switching on when ignition is activated;
• Automatic switching on of optics after ;
• using a special light sensor.

Each low beam automation scheme can be implemented in garage conditions. But if you do not have the necessary skills, doubt your capabilities, or simply want to get a guaranteed result, seek help from specialists.

On many foreign-made cars, the factory equipment already includes a special device that automatically turns the car's optics on and off. They work in tandem with a light sensor.

The device responds to changes in lighting levels. If the sensor detects darkening, . When the car is on a bright section of the road, it automatically turns off. In many countries this function is very useful and convenient. But not quite suitable for the Russian Federation.

It's all about the requirement to constantly, day and night, drive with low beams or daytime running lights on. Therefore, in this situation, the operation of the sensor has to be adjusted.

Turning the low beam on and off should become a habit for drivers in the absence of an automation system. If you forget about the lighting before you start driving, you may be fined. If automatic shutdown does not work or is simply missing, the lights on on a parked car will drain the battery by morning.

Drivers who cannot train themselves to turn lights on and off as needed are best off using an automation tool. One of them is considered a special sensor.

Motorists have the option to choose from self-made devices, or purchasing a branded device. Here we definitely need to stick to the second option. The following recognized companies offer automatic headlight switching and switching devices:

• Premier;
• Quatoom.

Most devices are based on a light sensor. And this, as you already remember, does not comply with the traffic rules in force in the Russian Federation. This is not a problem, since some devices are reconfigurable, allowing you to adapt them to slightly different work.

There is no need to describe in detail the nuances of installing a device with a light sensor. Each manufacturer completes its products detailed instructions. They may differ from each other in the installation method. But in reality there is nothing complicated here.

Experienced drivers advise installing the light sensor not outside, but towards the interior, in the area of ​​the rear view mirror, where it is usually located on cars with factory-made sensors.

Among the options presented, installing a sensor is considered the least practical and rational way to automate the switching on and off of optics. Yes, in certain situations the device greatly simplifies driving, since the driver does not have to be distracted by switches.

But at the same time, light sensors do not always adequately respond to the traffic situation. Some road sections can cause the controller to go crazy as dark areas quickly give way to light areas, and this happens constantly. As a result, the headlights turn on and off. It is unlikely that the traffic police will like this. And the driver himself will experience serious discomfort from such light and music.

Ignition

A good option for turning on the low beam automatically on a car involves using the ignition. The idea is for the headlights to turn on after .

To implement the circuit, you first need to connect the lighting fixtures to a power source. Since some devices are connected regardless of the position of the ignition switch, and others only after ignition, you need to choose the right source. The most preferable solution is a button to activate the stove.

To make the diagram work, you will need to take:

• set of wires;
• diodes;
• five-pin relay.

The kit is quite simple, and assembling everything you need will not be difficult.

After preliminary preparation, you can start working.

1. The switch is removed side lights. It is usually located on the leftmost switch block.
2. The positive wire is removed from the button block, which is responsible for the operation of the car's near optics. On most cars this is a double green wire. It is then connected to the relay.
3. The other positive wire that goes to the car heater switch is used to insert additional wiring into it. It also goes to the relay.
4. A wire is connected to the relay through which the optics will be powered.
5. The wire remains to be additionally thrown onto the body to make a minus.

Some additionally use soldering irons to improve the quality of the connection. But you don't have to do this. High-quality insulation using twisting and tape is quite suitable.

This scheme allows you to automate the process of starting the low beam as soon as the car’s ignition is turned on.

The automation scheme has certain disadvantages. The downside is the questionable cost-effectiveness of such a solution. The optics will start working as soon as you turn on the ignition. In winter, this function is of dubious benefit, since first you need to warm up the car for some time.

There is an option to avoid this drawback. But here we have to make the scheme even more complicated. The modification means that the low-beam headlights will turn off when the car is stationary. It doesn't matter whether the ignition works or not.

Engine

Those who are not satisfied with the option with a sensor and ignition can go a slightly different route.

You can use the engine start to turn on the low beam headlights automatically. Moreover, here the scheme is conditionally divided into 2 directions. They provide for connection to the handbrake or a sensor responsible for oil pressure.

Let's start with the connection option to the oil pressure sensor. To connect the circuit, you need to take:

• relay;
• a pair of transistors;
• wires;
• microcircuit K561TP1.

All components are installed in a compact relay housing. Next, the resulting device is connected to the oil pressure sensor. When normalizing pressure levels in power unit, which happens when the engine starts, the sensor will begin to open. The power going to it will go to the capacitor.

As a result, the voltage to our relay will go through the transistors connected to the power supply. When the engine turns off, power from the sensor goes to the necessary lamp, which is located on dashboard vehicle. At this moment, the capacitor included in the optics control unit will discharge. This cuts off the power supply to the relay. The light goes out.

This scheme allows you to control the near optics in automatic and manual mode. To do this, you will need to use an additional parallel connection.

The driver can independently set the time to turn off or turn on the low beam headlights. To achieve what you want, you only need to select the optimal resistance on the board. The higher the value, the longer the time will pass before turning on and before turning off.

But this method does not suit all drivers. There are many opponents to such a scheme. This is due to the rather high complexity of the connection, which is objectively a fair remark. After all, here you have to pull the wiring and make about 3-4 connections. If you are happy with this option and you are ready to implement it yourself, you can get to work.

Motorists who need a simpler option can use the second scheme. We are talking about connecting to the handbrake. Since we have already discussed the connection method through the ignition, there will definitely be no problems with the implementation of this circuit. Just a little bit of work is needed here.

The point of the modification is to add another relay. Plus, you will need a small wire about 250 millimeters long, which is connected to the standard contact on the handbrake button.

The principle of turning on and off the low beam with this scheme is extremely simple. If you apply the handbrake, the headlights go out. As soon as you lower the handbrake handle, the optics turn on.

Each motorist decides for himself which scheme to choose. The presented options do not require significant financial costs, and also do not imply that the car owner must have professional skills in working with automotive electrical systems.

But you need to be extremely careful and careful. Working with the wiring and electrical components of a machine is always delicate and requires concentration and consistency.

Many question the relevance of the automation system for turning on and off the low beam of a car. They are sure that it is much easier to develop the habit of monitoring the optics, rather than trying to alter the car’s electrical circuit to suit your comfort. We can partially agree with them, since even such automation has certain disadvantages.

And if you previously easily managed without automatically turning on the light, then now there is no urgent need to change anything. But the choice is still yours.
