For the 2005 Dodge Magnum, the supplied fitment data lists a 9005 bulb for the high beam and daytime running light. No low-beam bulb is specified in the available data, so verify the headlamp assembly before ordering a replacement. The data does not identify a projector or non-projector headlight distinction.
Other useful exterior bulb sizes include 3457A for the front turn signal and parking light, 194NA for the front side marker, and 3157A for the rear side marker. Rear lighting uses 3157R for the brake and tail lights, while the rear turn signal takes 3757A. The reverse light uses 921. The center stop light is listed as LED rather than a replaceable bulb size.
For interior and auxiliary lighting, the supplied data lists 578 for the dome, map, and trunk lights, 194 or 7441 for the glove box, and 2825 or 98 for the license plate and courtesy lights. Confirm the original bulb and socket where multiple options are shown.
