For the 2007 BMW X3, the listed low-beam headlight bulb is D1S. No separate high-beam bulb fitment is provided in the supplied data, so verify the original bulb before ordering a replacement for that position.
Front fog light fitment is listed with two options: H11 LED and H16 LED. Compare the existing bulb and socket to determine which option applies to your X3.
- Front turn signal: 5200 or 2827
- Rear turn signal: 7507
- Reverse and brake lights: 921
- Center stop, tail light, and rear side marker: LED assemblies
- License plate, dome, and glove-box lights: 6418
- Parking and front side-marker lights: 2825 or 98
- Courtesy lighting varies: compare the original for either 2825/98 or 6411/6428
Because several positions have multiple listed options, match the replacement to the bulb currently installed before purchasing.
