For the 2007 Honda Ridgeline, the low-beam and high-beam headlights both use a 9003 bulb. The supplied fitment data does not specify a separate bulb for projector or non-projector headlight housings, so confirm the housing configuration before ordering.
Fog-light fitment is listed with two LED options: H11 LED and H16 LED. The front turn signals, parking lights, and front side markers use 3457A. At the rear, the tail and brake lights use 7443R, while the rear turn signals use 7440 and rear side markers use 7443A. Reverse lights take 921 bulbs.
Interior listings include 2825 or 98 for the dome light, DE3175 for map lights, and DE3021 for the glove box. Center-stop, license-plate, and trunk-light fitment is listed as 168 or 917; verify the original bulb where multiple options are shown.
