For the 2003 Nissan Frontier, the low-beam and high-beam headlights both use a 9007 bulb. The supplied fitment data does not indicate a separate bulb or a projector/non-projector headlight distinction, so 9007 is listed for both beam functions.
- Fog lights use 899 bulbs.
- Front turn signals use 3456 bulbs.
- Rear brake and tail lights use 3157R bulbs, while rear turn signals use 3157A bulbs.
- Reverse lights use 3156 bulbs.
- The center stop light, dome light, and trunk light use DE3175 bulbs.
- Front side markers use 168NA bulbs.
- License plate lighting is listed with either 194 or 7441, and parking lights are listed with either 168 or 917. Check the existing bulb or socket when replacing these applications.
Verify the bulb number on the vehicle before ordering, particularly for applications where more than one size is listed.
