BULB - CAB AND CHASSIS





NOTE: The rear lamp unit contains up to seven bulbs: rear side marker (3), turn signal (4), brake lamp (5), park/tail (6), license (8), backup (9) and, on the driver side only, a rear fog lamp (7). The service procedures for each bulb are the same, only the bulb sizes and types may differ.

1. Disconnect and isolate the battery negative cable.
2. Remove the four screws (1) that secure the lens (2) to the rear lamp unit housing.
3. Remove the lens from the housing.
4. Push the ineffective bulb (3, 4, 5, 6, 7, 8 or 9) slightly toward the socket and rotate it counterclockwise about 30 degrees to unlock it.
5. Pull the base of the bulb straight out of the socket.
