Brake Lamp: Description and Operation

Battery voltage is applied to the noise suppression filter #1 and the brake switch at all times from the STOP LIGHT fuse CB-13. With the brake pedal depressed, the brake switch is closed and battery voltage is applied to the brake lights, and the brake lights go on. The high mounted stop light is made up of 84 LEDs arranged in 21 parallel circuits; each parallel circuit is made up of 4 LEDs and 2 resistors in series. The noise suppression filters are placed in the brake lights circuit to reduce interference with the sound system.
