For the 2002 Toyota Sequoia, the low-beam and high-beam headlights both use a 9003 bulb. The supplied fitment data does not identify a projector or non-projector headlight variation, so confirm the original bulb before ordering if your housing has been changed.
Other useful exterior bulb sizes include:
- Front turn signal, parking light, and front side marker: 3157A
- Rear turn signal: 7440
- Brake light: 7443R
- Rear side marker: 7443A
- Reverse light: 921
- Tail light: 168, 917, or 7443R, depending on the specific position
The center stop light and license plate light may use either 168 or 917 bulbs. Interior fitment also includes a DE3175 dome light and trunk light, plus a 37 glove-box bulb. Map lights use 194 or 7441. For the courtesy light, compare the original bulb: the listed options are 194 or 7441 for Option 1, and DE3021 for Option 2.
