1999 Toyota 4Runner bulb fitment
The low-beam and high-beam headlights both use a 9003 bulb. The supplied fitment data does not identify separate headlight configurations, so use 9003 for either beam position.
- Fog lights may use H3 or H3C; compare the existing bulb and socket before ordering.
- Front and rear turn signals use 7440 bulbs.
- Brake and tail lights use the red 7443R bulb, while the center stop light uses 921.
- Reverse lights use 7440.
- Parking lights, front side markers, and license plate lights may use 2825 or 98; match the bulb currently installed.
- Dome and trunk lights use DE3175, and the glove-box light uses 2721.
- Instrument-panel fitment includes 158, 194, 7441, or 2721 depending on the original setup. Compare the original bulb carefully before replacement.
