WARNING: This page is about a different car, the 2015 RAM 3500 HD and 2015 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Always use the correct bulb size and type for replacement. An incorrect bulb size or type may overheat and cause damage to the lamp, the socket or the lamp wiring.
NOTE:
The Center High Mounted Stop Lamp (CHMSL) may house up to three bulbs. The center bulb is the CHMSL bulb and illuminates through a red lens, while on vehicles so equipped the two outboard bulbs are for the cargo lamps and illuminate through clear lenses. The bulb types and service procedures are identical for all three of these bulbs.
- Align the base of the CHMSL bulb (2) with the socket (3).
- Push the bulb straight into the socket until the base is firmly seated.
- Align the socket and bulb with the keyed opening on the back of CHMSL housing (1).
- Insert the socket and bulb into the housing until the socket is firmly seated.
- Rotate the socket clockwise about 30 degrees to lock it into place.
- Position the CHMSL into the opening in the rear cab roof header panel.
- Install and tighten the two screws that secure the CHMSL to the rear roof header inner panel. Install the screw on the right side of the lamp first, followed by the screw on the left side of the lamp. Tighten the screws to 2.5 N.m (24 in. lbs.).
- Reconnect the battery negative cable.
