Brake Lamp: Description and Operation

The stoplamps consist of the center high mounted stoplamps and the LH and RH rear stop/turn lamps. The LH and RH rear stop/turn lamps are single- filament bulbs that are used as stoplamps and turn signal lamps.

The stoplamp switch receives battery voltage at all times through the STOP LAMPS fuse. When the brake pedal is pressed, the stoplamp switch closes and battery voltage is applied to the center high mounted stoplamps through the stoplamp switch signal circuit. The stoplamp switch signal circuit also sends battery voltage to the turn signal switch. The turn signal switch applies voltage to the rear stop/turn lamps through the turn signal lamp signal circuit, using the stop/turn signal lamps as stoplamps. The center high mounted stoplamp and the stop/turn signal lamps are permanently grounded.
