The brake light is on every car. However, the day (and especially during Sunny weather), the light becomes less visible. My suggestion is to use for signaling braking and still the Parking lights (so much so that at dusk and at night, they automatically would go to work in the usual, regular mode). For this customization requires minimal intervention in the scheme of the onboard network of the car, and here is the result… In its high efficiency will make sure everyone who is brought to follow the car, stop signal, in which the day is highlighted by a “retrained diodes dimensions”.
Indeed, when braking in the daytime at work, in addition to the former of the two brake lamps are included (see updated schematic diagram) overall ЕL1 and ЕL4 — through semiconductor diode VD2. The purpose of the diode VD1 to prevent passage of current from the brake light circuitry to the front marker lights.
