Brake Lamp: Description and Operation
STOP LAMPSWhen the driver presses the brake pedal, all stop lamps will illuminate.
The STOP/HAZ fuse in the IP fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery voltage is supplied to the stoplamp relay. The stop lamp relay distributes the voltage to the turn/hazard switch which in turn sends battery voltage to the rear stoplamps. The stop lamp circuits use a dual filament, single bulb turn/stop lamp system.
