For the 2004 Chrysler Pacifica, the supplied fitment data lists a D2S bulb for the low-beam headlight. No high-beam bulb size is provided, so verify the high-beam housing or consult the vehicle documentation before ordering a replacement. The data does not identify a projector versus non-projector headlight variation.
Useful exterior replacements include 3157A for the front turn signal and parking light, 194NA for the front side marker, and 168NA for the rear side marker. Rear lighting uses 3157R for the brake and tail lights, while the rear turn signal uses 3157. The reverse light takes a 921 bulb.
For other lighting, the center stop lamp is listed as LED. License plate fitment includes 168 and 917, while interior applications include 194 or 7441 for the courtesy and glove-box lights and 578 for the dome, map, trunk, and other interior lights. Confirm the existing bulb and socket where multiple options are listed.
