For the 2014 RAM 2500, the high-beam headlight uses a 9005 bulb. Low-beam fitment depends on the headlight design: trucks with projector-type headlights use 9012, while trucks without projector-type headlights use H11. Confirm which headlight style is installed before ordering the low-beam bulb.
Several exterior lighting positions also vary with the projector-type configuration:
- With projector-type headlights, front and rear turn signals, parking lights, side markers, tail lights, and brake lights are listed as LED, while reverse lights use 7440.
- Without projector-type headlights, front turn signals, parking lights, and front side markers use 3157A; rear side markers use 3057A; rear turn signals use 3157; and tail and brake lights use 3157R. Reverse lights use 921.
- The center stop light and trunk light use 921, the map light uses 578, and the engine light uses 561.
- License plate and glove box applications are listed as 194 or 7441.
