Brake Lamp: Description and Operation
Voltage is supplied at all times through the STOP-HZ Fuse to the Stoplamp Switch. When the brake pedal is depressed, the contacts in the Stoplamp
Switch close. Voltage is supplied through the Turn Signal Switch to the LH and RH stoplamps, and the Stoplamps go on. If a turn signal is on, the
Stoplamps on that side will flash as a Turn Signal. The other Stoplamps will serve as a Stoplamp.
