For the 2002 Toyota Tacoma, both the low-beam and high-beam headlights use a 9003 bulb. The supplied fitment data does not identify a separate bulb for low and high beam, so use 9003 for either headlight function.
Other notable exterior lighting includes 4157NA bulbs for the front turn signals and parking lights, with 168NA used for the front side markers. At the rear, the brake and tail lights use 1157R, the rear turn signals use 1156, and the reverse lights use 921.
- The center stop light may use 168 or 917.
- The license plate and instrument lighting may use 194 or 7441.
- For the courtesy light, compare the original bulb before ordering: the listed options are DE3021 and DE3022.
- The dome light uses DE3175.
