For the 2008 Toyota Tundra, the low-beam headlights use H11 bulbs, while the high beams use 9005 bulbs. The supplied fitment data does not list a fog-light bulb. No projector or non-projector headlight variation is specified, so verify the original bulb before ordering if the truck has modified or replacement headlamps.
Several exterior lighting functions use replaceable automotive bulbs. Front turn signals, daytime running lights, and parking lights use 4157NA. The front side marker uses 168NA. At the rear, the brake and tail lights use 3157R, while rear turn signals and rear side markers use 3157A. Reverse lights and the center stop light use 921.
Interior and auxiliary fitment includes 168 or 917 for the dome and map lights, with the same options listed for door-mirror lighting and license-plate illumination. The glove box and step lights use 2721. Ash lighting may use 2721 or 74; compare the original bulb before replacement.
