Hello. I needed a diagram of automatic switching on the low beam or dipped beam, on a foreign car. Searched on the internet. There are circuits that respond to an oil pressure light going out, on the dash. But I do not like it as something, because the lamp can be on the road and lit, especially at the limit of the engine, and mount a block on the relay is not reliable, and do not want to. I don’t want to bother with relays, why do I need extra contacts? I’ve seen schemes that work on signals for the tachometer, but I’m afraid it won’t work for a foreign car. The tachometer can start to lie, or worse – the computer can’t correctly read data from the crankshaft position sensor. I don’t want to take any chances, as ECU is not cheap. But if you connect to the alternator, I think there should be no problems, especially if you connect to the field winding, but the question of how to do it, I have not thought of yet. It is desirable and with time delay as for 5 seconds. Maybe someone will tell me what to do.

I hooked the exhaust light to the contact of gas pump relay (the one which is not under plus until the relay turns on), at the same time and the relay is controlled by the serviceability.

If you have a low oil pressure light on, especially in extreme conditions, it means it’s time to overhaul the engine

High quality at a competitive cost allows MORNSUN DC/DC converters to compete with counterparts from the world’s leading manufacturers. Products of this brand, such as the UWTH1D family, can be successfully used in railway applications. For telecommunications equipment are suitable DC/DC-converters of VCB and VCF families, for distributed power supply systems – K78 family small-sized pulsed PoL-stabilizers, and for automated production systems and robotics – KUB series is indispensable. There are also unique solutions, such as miniature DC/DC converter B0505ST16-W5 in a chip design for medical devices.

The battery is the best way to connect it to the battery, why bother with connection to sensors, brains, etc., and drag wires from who knows where, it is easier and more reliable to connect it only to the battery.

I have a Phillips LED. It is connected to the battery and the lights directly. Block monitors the voltage to the acb. and happens that when the ignition is off lights re-initiated on and off. apparently react to the drop in voltage on the acb. unleashed the brain brain DXO relay on the ignition chain. but given the staff light sensor – works perfectly. Kalyna universal. configuration ХХХХХ-038-38.

According to GOST, the Iho should turn on when the car is ready to move. i.e. key turned – Iho on, until the light is on. key off – lights are not on.

I had to connect to the alternator terminal for adequate work, because when you connect to the acb did not always turn on.

You can also hook up to the pump in the tank, it’s a good idea, just pick up a time relay for 12V. I think this relay will do

_________________ When it seems you understand everything, it turns out that you don’t know the half of it!

I would use one of these with on/off/time control. You can adjust the balance between on/off with a capacitor and total time, diode input, maybe you can take a bigger one.

_________________ When it seems you understand everything, it turns out that you don’t know the half of it!

The ratio of charging / discharging time of the capacitor, which corresponds to the on / off time a capacitor should be 1000 uF and a 15-20k resistor in parallel

I built a circuit for a time relay, but the time control does not work. Isn’t there something similar only on N channel MOSFET transistor.

_________________ When it seems you understand everything, it turns out that you don’t know the half of it!

Or use samsung’s circuit, it’s better than mine, its on/off time depends on R1, if you want to change the turn off time you have to put a diode at the input, and a capacitor shunted with a resistor that will discharge the capacitor.

I connected it to the oil pressure drop sensor. This is inconvenient: when you start the engine, they are already on. Therefore I will connect to speed sensor and introduce delay for switching off 30-40 sec. and also they can be switched on from cabin, in this case delay will be 10 minutes. Another consideration – the introduction of undervoltage protection (starter turns). Such things. And yes, the criterion for turning off is not the parking lights, but the dipped and/or high beam.

_________________ Before it gets better, the situation gets worse. TDA7294 + 350W DUT + Orbit 35AC-016 = the whole neighborhood dances.

I used this circuit. You can pick up the capacitance as you like. Even if the oil pressure lamp will be flashing, the capacitor has no time to discharge, and the headlights will not flash.

This is a working scheme, the firmware is simple, it takes half a day to write, so on principle I do not lay it out.

It has more details, but it has “brain” and I don’t have to think about it, it decides when to turn on / off, and I’m not afraid that someday I’ll be very “happy” with low battery from the forgotten headlights.

Schemes of wiring the headlights

Daytime Running Lights are a must for driving on the road in the daytime. They are necessary to improve the safety of drivers, and reduce the statistics of accidents. Lights provide catchiness and expressiveness of the car, making it visible to other road users. Therefore, it is necessary to install lights, and for this you need to know how to connect the running lights, the scheme of their connection. DRL scheme may not be one, there are a lot of them. One scheme for installing daytime running lights can be simple for you, but another scheme for installing DRLs is complicated. Also, one daytime running lights installation scheme can be done in a few minutes, while another daytime running lights connection scheme will require you to work with a soldering iron and expend a lot of effort. But, it is worth noting that each scheme – automatic activation of daytime running lights is quite feasible on its own. We will tell you the most common and fairly easy schemes for connecting daytime running lights, which will independently and quickly get a stylish and practical device, as well as a security product.

Scheme of activation of daytime running lights at the beginning of movement and stop.

This scheme is suitable for all Russian cars. All cars are marked with parking lights, which corresponds to the requirements of traffic rules and the law. In such cases, the source of movement is a sensor that determines the speed of the car.

Thus, you need to follow this plan:

Contacts 1.1 of the automatic – dipped beam control unit should be plugged into the wiring gap from the switch to pin 85 of the RBS. If you need to turn the dipped beam on when parked, then you will need to “parallelize” the contacts responsible for this.
Relay K1 – must be with vehicle code 851.3747. But, experts say that you can use any relay that provides an opening pair of contacts, as well as stably working at a voltage, namely from 6 to 14 V.

In order to see the scheme in more detail, just click and enlarged version will open in a new window.

Scheme for switching on the running lights: the use of PTFs.

For the car VAZ 2110, the scheme for connecting the low-beam headlights in this way is ideal. For this purpose, it is initially necessary to disconnect the regular circuit, which included fog lights and do a little reworking, making it so that it provides activation of the glow after ignition of the car. For this purpose, any thyristor, for example, with a current of 0.3 A may be suitable. It is recommended to choose a capacitor of 1500 μF 25 V, which will provide even up to 23 seconds of activation delay. For the resistors it is mandatory to have a power of 0.25W and 10Kohm. This circuit can easily fit in a relay box, and can be placed in a wiring block. How to proceed:

Initially, you must disconnect the minus wire that is on the winding of the relay, which provides the activation of the window lifters and make its insulation.
Find the wire that comes from the fog lights button. Deactivate it and remove it from its original place, putting it on the disconnected wire in the first point.
After that, you can insert the finished design back into the socket.

Scheme of connecting the DRL when igniting the motor of the car.

The scheme is used for many cars and is ideal for VAZ 2110. The essence of this scheme is that a special jumper is put on the relay from the fog lights from the field winding supply.

Remove dashboard from the car
Pull out the button responsible for activation of PTF.
Disconnect the angled wire from the plug.
Connect it with the necessary wire responsible for automatic lighting when the car engine is on.
Insert in the free space on the plug and return the button to its original location.

In order to see the scheme in more detail, just click and enlarged version will open in a new window.

Such a wiring diagram for the connection of the exhaust lights from the generator will ensure the automatic activation of the glow of the devices. It is worth noting that the scheme for connecting the running lights is suitable in the event that you use fog lights for this purpose. If you do everything correctly, then when you turn on the alternator of the car – the light comes on, and when you turn off – goes out. At the same time, the lights are activated by the button, and the ignition switch remains open.

Diagram of connection of the low-beam headlights.

The principle is similar to the above, that is, it is the third scheme, the daytime running lights will also automatically turn on when the car is ignited, but now together with the dipped beam. The lights are switched off after stopping, and the parking lights remain inactive. The rest of the lighting systems remain in the same mode. Action steps:

Initially, you will need to arm two LEDs of minimum power, such as 1A – KD10. They should be connected in series.
Next, you should solder a wire to them, the length of which will be an average of 40cm.
Disassemble the dashboard of the car, in order to connect the workpiece to pin 12 of the connector X1. Often the color of the wire is yellow.
Take out the button responsible for turning on the lights.
Connect to the green wire of the connector (this is often the color) with your billet. Alternatively, you can insert a stripped wire into the socket of the connector.
After that, put the button back in its place and check that the system works.
If you need to make a stop with the engine running, but with the parking lights on and the dipped beam off, then you need to insert this button in the slot of the wire.

Diagram of the DRLs: automatic switching on/off, depending on the generator.

This circuit diagram of the running lights was tested on the Lada Priora and on the VAZ 2110, where in both versions worked perfectly.

The first circuit in the figure is designed in the case when the work is related only to the handbrake and the motor.
The second circuit in the figure has an additional resistor, which is responsible for switching off the daytime lights when the operation of parking lights or headlights is activated. This is done by feeding a “+” to the base of the transistor number KT814.
The third proposed scheme provides deactivation of burning of daytime running lights in the following cases: if the handbrake is raised (when starting the engine or for its automatic activation with the alarm); if the lights are on (then the lights or fog lights are transferred to normal mode). Simply put, this scheme of activation of daytime running lights cancels their automatic start together with the ignition of the generator. It is worth noting that this scheme of connecting the daytime running lights with the disabling of automatic function has passed the GTO.

Running lights scheme: automatically turn on with the ignition and deactivation when the dipped beam or lights are on.

The scheme is suitable for many cars and is ideal for VAZ 2110. This variant uses an oil pressure sensor, which is taken from the socket in the dashboard of the car. The signal to start the engine comes from this sensor. At the same time, if you activate the lights, or turn on the dipped beam, then the lights are automatically extinguished.

Diagram of connection of the low-beam headlights through a relay: function of damping of the light intensity.

When ignition is automatic, but if you turn on the dipped beam or fog lights, then the sidelights reduce the intensity by 1/3. When running lights – the lights continue to emit light actively. The principle of this operation is to switch the relay 2, when activating the value at the time of turning on the dipped beam and the fog lights. Also, a resistor, which is located in front of the lights on the same field wire, coming from the dipped and fog lights, is involved in this process. You can use a diode for this, so that the power from one device does not go to the other.

Scheme of switching on the sidelights with a delay of 7 seconds after ignition.

With this scheme, the sidelights go off when the parking lights are activated, and when the engine is off. If you blink high beam, then the lights will not go out, and besides the load on the electrical circuit, this scheme also does not add. Actions:

On the wire coming from the dash – put a button. This is necessary in order to comply with GOST, which requires the ability to manually turn off. Territorially it can be placed next to the block, which is responsible for controlling the heating.
Приобретите специальные колодки реле, для того, чтобы удобней производить монтаж. Необходимо на клипсы подсоединить к блоку предохранителя собранную схему./li>
It is most convenient to assemble the circuit in the case, while making sure that the relay is deactivated. Only 5 wires are assembled: from the exhaust lights, from the lights, from the constant “+” and constant “-“, as well as from the motor lamp, through a special button.
You can use a 5-pin or 4-pin relay. In a non-working relay remove all the contents and solder the “timer” on the contacts of the coil.

Note

If these circuits are very difficult for you and working with electrical circuits is difficult, then you can buy ready-made controllers, i.e. control units that provide automatic switching on of your dimming lights and many other functions. Also, all the modern sets of siren lights already come with this block, which has only 3 wires and is easy to connect in the car. And how to do it correctly, you can learn in the article “Rules for installing and connecting the sidelights”.

QUESTION: Do I need to connect a separate voltage regulator for my remote lights? _______________________________________________________________________________________________________________________________________________________________ ANSWER: Hi, Nikolay. If you are installing certified amber LEDs, they already have a voltage regulator. What can not be said about the homemade daytime running lights.

Here is a finalized scheme, but you can add something else if you want, such as a light sensor, or something else. It should be pretty clear. http://s8.hostingkartinok.com/uploads/images/2016/04/f684cc60a166332456a86513f601f16a.bmp
