For the 2010 Ford Explorer, the same H13 bulb is listed for both the low-beam and high-beam headlights. The supplied fitment data does not identify a projector or non-projector headlight variation, so verify the existing bulb before ordering if your vehicle has replacement housings or modified lighting.
Other useful exterior fitments include 3457A for the front turn signal and parking light, 4057 for the rear turn signal, and 921 for the reverse light. The brake light uses 4057R. Tail-light listings include 4057R, 194, and 7441, indicating that more than one bulb position or assembly may be involved. The center stop light is listed with 2825 and 98 options, while license-plate and courtesy/interior applications may use 168 or 917. The dome, map, and trunk lights use 578 bulbs.
