Brake Lamp: Description and Operation
Voltage is applied at all times through the STOP-HAZ Fuse to the Brake Switch. When the brake pedal is depressed, the contacts in the
TCC/Stoplamp Switch close. Voltage is applied through the Turn Switch Assembly to the LH and RH Stoplamp, and the Stoplamp lights. If a Turn
Signal is on, the Stoplamp on that side will flash as a Turn Signal. The other Stoplamp will serve as a Stoplamp.
