For the 2001 Toyota Tacoma, both the low-beam and high-beam headlights use a 9003 bulb. The supplied fitment data does not identify a separate projector or non-projector headlight variation, so verify the original bulb before ordering if the truck has replacement headlamp assemblies.
Front turn signals and parking lights use 4157NA bulbs, while the front side markers use 168NA. Rear lighting includes 1157R bulbs for the brake and tail lights, with 1156 bulbs for the rear turn signals. The reverse lights use 921 bulbs.
- Center stop light: 168 or 917, depending on the original setup.
- License plate and instrument lighting: 194 or 7441.
- Courtesy light: compare the original bulb to DE3021 or DE3022 before replacement.
- Dome light: DE3175.
Match the replacement to the bulb currently installed, especially where more than one option is listed.
