For the 2010 Ford Expedition, both the low-beam and high-beam headlights use an H13 bulb. The supplied fitment data does not identify a projector or non-projector headlight variation, so confirm the existing bulb and housing before ordering.
The front turn signals and parking lights use 3157A bulbs. Front side-marker lighting uses a 194NA bulb, while the rear side marker uses 4157NA. At the rear, the tail lights use 4157R bulbs, and the rear turn signals use 4157 bulbs.
- Reverse lights: 921
- Brake lights: 4157R
- Center stop light: 2825 or 98
- License plate lights: 168 or 917
No fog-light bulb is listed in the supplied data. Because the center stop and license-plate locations show alternate bulb numbers, compare the removed bulb or socket with these listed options before purchasing.
