Smoothly turning on the headlights can be done by yourself

If you've ever been in a theater or circus, you probably noticed that the light before the presentation starts to go out slowly, that is, not immediately, but smoothly. Accordingly, it is also included, this is done in order not to blind the spectators. This is due to the rheostat, with its help the voltage is distributed to the light bulbs. The same effect is a smooth light on and off Can be seen on some cars.

This can be achieved with a special device. What will it give us? Of course, the lamps will last us longer, and their resource will increase. As a rule, a person's eye adapts gradually to light. Therefore, the smooth inclusion of headlamp light will not blind the drivers of cars or pedestrians in front or in front. And the load on the retina of the eye will be minimal, which is no less important for human health. In addition, it's beautiful (a kind of tuning) and convenient.

With the method of ordinary lamp switching, the voltages are more than expected according to generally accepted standards. As a result, the lamp burns, as the filament of the incandescence breaks off. The smooth inclusion of light makes it possible to extend the life of the lamp, since the supply of voltage along the spiral occurs in the minimum volume. The light control circuit can be placed in the same place as the standard light relay. And in the event that something does not suit you, it will be possible to easily return everything to its original form.

To make the device, by means of which the headlamps will turn on smoothly, you need to purchase a relay with a capacity of 12 volts for each of the lamps. Resistors (0.1-0.5) must be selected for the main characteristics of the relay, and they must operate at maximum current. To avoid overloading and failure of the resistors, it is necessary to purchase a resistor with a ceramic base, power of 5 watts, since the circuit will have a large current flow.

Installation of the device will be as follows. We take two relays and place, where there is free space, near the headlights on the body, with soldered resistors on the wires of the bulbs. We pass through the relay contacts of the lamps, which we have obtained with resistors and the power contacts bend. Then you need to connect the output and input wires with the headlight contacts. To completely finish the device, by means of which the light will turn on smoothly, it must be checked beforehand. If everything is good, and the device is working, you can start making a protective cover for the relay.

The shape and size of the casing are possible. For example, the casing of the box from the counting sticks of plastic, which we once used in school. Make two holes in the box (for the output of the wires), insert and fasten the relay on the body. To avoid water ingress, fill the slots with a sealant. Check again, and now the smooth inclusion of light will not cause any inconvenience to the other participants in the movement. This device will be useful for all transport enthusiasts. And with this device, the transistor of the car almost does not heat up.
