2002 Toyota Tundra bulb fitment starts with the headlights: both the low-beam and high-beam functions use a 9003 bulb. The supplied fitment data does not specify a projector or non-projector headlight variation, so verify the original bulb before ordering.
- Front turn signals, parking lights, and front side markers use 3157A bulbs.
- Rear brake and tail light fitment may be either 3157R or 7443R. Compare the original bulb before replacement.
- Rear turn signals may use 3156 or 7440A, also requiring comparison with the original.
- Reverse lights and the center stop light use 921 bulbs.
- License plate lighting may use 168 or 917 bulbs.
- Interior applications include DE3175 for the dome and map lights, 37 for the glove box, and 921 for the trunk light.
- The step light uses 2721.
Because several rear and interior locations have listed alternatives, match the bulb base, size, and function to the bulb currently installed in your Tundra.
