For the 2008 BMW X3, the supplied fitment data lists a D1S bulb for the low-beam headlight. No high-beam bulb size is provided, so confirm the high-beam application before ordering or replacing that bulb.
Fog-light fitment includes two listed options: H11 LED and H16 LED. Check the existing fog-light socket and vehicle configuration to determine which option applies. Other notable lighting details include:
- Front turn signals: 5200 or 2827
- Reverse and brake lights: 921
- Center stop light, rear side marker, and tail light: LED assemblies
- Rear turn signals: 7507
- License plate lights: 6418
- Parking and front side-marker lights: 2825 or 98
Because several positions have alternate listings, compare the removed bulb or socket with these options before purchasing. The supplied data does not identify which specific vehicle configuration uses each alternative.
