Brake Lamp: Description and Operation

STOP LAMPS

When the driver presses the brake pedal, all stop lamps and the auxiliary brake warning lamp will illuminate.

Fuse #12 supplies battery voltage to the stoplamp switch at all times. When the brake pedal is pressed, the stoplamp switch supplies battery voltage to the LH and RH stoplamps and the auxiliary brake lamp. The LH and RH stoplamps and the auxiliary brake lamp are permanently grounded to G400.
