A brake light switch allows the brake lights or tail lights to turn on or give off greater illumination once the brakes are used. It is also used to activate third brake lights or light bars. When the brake pedal is pressed, the brake light switch closes, allowing current to flow, which in turn activates the brake light system of the vehicle to signal other drivers that the vehicle is slowing down or coming into a complete stop.
