For the 2009 Dodge Ram 3500, headlight bulb fitment varies by headlight configuration. The low beam may use an H13 or H11 bulb, while the high beam may use an H13 or 9005 bulb. Check the existing bulb or headlight housing before ordering, since the listed options are not interchangeable without confirming the installed setup.
Other useful exterior bulb sizes include:
- 3157A for the front turn signal, parking light, and front side marker
- 921 for the reverse light
- 168 for the license plate light
Interior and utility lighting uses several different sizes. The dome light takes a 578, the engine compartment light uses a 561, and the glove box uses a 194. The map light may use either a 194 or 212-2; compare the original bulb before replacement. The ashtray light uses a 37, and the listed trunk light uses a 912.
