2009 Ford Expedition bulb fitment uses an H13 bulb for both the low-beam and high-beam headlights. The supplied fitment data does not identify a separate headlight type or projector-specific variation, so confirm the existing bulb before ordering.
- Front lighting: Front turn signals and parking lights use 3157A bulbs, while the front side markers use 194NA.
- Rear lighting: The reverse lights use 921 bulbs. Tail lights and brake lights use 4157R, rear turn signals use 4157, and rear side markers use 4157NA.
- Center stop and interior: The center stop light, courtesy lights, and map lights are listed with 2825 or 98 options. The dome and trunk lights use 578.
- Other locations: License plate lighting is listed with 168 or 917 options, and the glove-box light is listed with 194 or 7441 options.
Because several locations show more than one supplied bulb number, compare the removed bulb and socket before replacing those applications.
