Brake Lamp: Description and Operation

STOP LAMPS

The STOP fuse in the fuse block - left underhood supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close. The battery positive voltage flows to the left stop lamp assemblies, to the right stop lamp assemblies, and to the center high mounted stop lamp (CHMSL). The left, the right stop lamp and the CHMSL have ground at G400 and G402.
