For the 2004 Toyota Avalon, the supplied fitment data lists a 9005 bulb for the high beam. The same 9005 size is listed for the daytime running lights. No low-beam bulb is provided in the available data, so verify the original low-beam bulb before ordering a replacement. No projector or non-projector headlight distinction is specified.
Other notable exterior lighting includes an 1157A bulb for the front turn signal, parking light, and front side marker. The rear turn signal uses 7440A, while the brake light uses 7443R. Reverse and center stop lights both use 921 bulbs. License plate and tail-light fitment includes both 168 and 917 listings, so confirm the installed socket and housing.
Interior applications include 6418 for the courtesy, dome, and map lights, 37 for the glove-box light, and 2825 or 98 for the trunk light. The rear side marker is listed as 194NA.
