Brake Lamp: Description and Operation

CIRCUIT OPERATION
The STOP Fuse is supplied with voltage at all times. When the Brake Pedal is depressed, voltage is applied through the Stoplamp Switch to the LH Stoplamp, RH Stoplamp and the Center High Mounted Stoplamp. All of the Stoplamps are permanently grounded. When power and ground are supplied to the Stoplamps, they light.
