2008 Ford F-150 bulb fitment starts with H13 bulbs for both the low-beam and high-beam headlights. The supplied fitment data does not identify a separate projector or non-projector headlight variation, so compare the original bulb and socket before ordering.

- Reverse-light fitment varies: compare the original bulb to determine whether your truck uses 3156 or 912.
- Brake and tail lights use 4057R bulbs, while rear turn signals and rear side markers use 4057 bulbs.
- The center stop light uses a 921 bulb, and the trunk light also uses 921.
- Front side markers use 194NA bulbs.
- License-plate lighting may use 194 or 7441; compare the original bulb.
- Dome-light fitment may be 578, 6411, or 6428, and map-light fitment may be 194, 7441, or 906 depending on the original setup.
Check the removed bulb against these options before replacing interior, reverse, or license-plate lights.
