For the 2003 Jeep Liberty, the low-beam and high-beam headlights both use a 9007 bulb. This shared fitment means one 9007 bulb type serves both headlight functions. The supplied fitment data does not identify a projector or non-projector headlight variation, so verify the existing bulb and housing before ordering.
Other key exterior lighting uses include:
- Front turn signals, parking lights, rear turn signals, and reverse lights: 3157
- Brake and tail lights: 3157R
- Center stop light: 921
- Front side marker: 168NA
- License plate: 168 or 917
- Step and courtesy lights: 906
Interior applications include a 212-2 dome and trunk light, 194 or 7441 map lights, a PC74 instrument bulb, and a 161 ash light bulb. No fog-light bulb fitment is listed for this model year in the supplied data.
