For the 2008 Dodge Ram 2500, the low-beam and high-beam headlights both use an H13 bulb. This dual-function fitment means the same H13 bulb serves both headlight functions, so verify the original bulb and connector before ordering.
The fog lights use 9006 LED bulbs. Exterior lighting includes 3157A bulbs for the front turn signals, parking lights, and rear turn signals. The front side markers use 2825 bulbs. For the rear lamps, the brake and tail lights use 3157R, while the reverse lights use 921 bulbs. The center stop light also uses a 912 bulb, and the license plate lights use 168 bulbs.
Interior and utility lighting includes a 578 dome-light bulb, 37 courtesy bulbs, and 561 engine-compartment lighting. The glove-box light uses 194. Map-light fitment has two listed options—194 or 212-2—so compare the replacement with the original bulb before purchasing. The trunk light uses 912.
