For the 2010 BMW X3, the supplied fitment data lists a D1S bulb for the low-beam headlight. No high-beam bulb is listed in the available data, so verify the original bulb before ordering for that position.
Front fog-light fitment is listed as either H11 LED or H16 LED. Check the existing fog-light bulb and housing configuration to determine which option applies. Other exterior fitment details include:
- Front turn signal: 5200 or 2827
- Rear turn signal: 7507
- Reverse and brake lights: 921
- Center stop, tail light, and rear side marker: LED
- License plate and dome/glove-box lights: 6418
- Parking and front side-marker lights: 2825 or 98
Interior applications also vary by location. Courtesy lights may use 2825/98 or 6411/6428 depending on the original bulb, while map lights use 2886X and reading lights use 6486X. Compare replacement bulbs with the originals where multiple options are shown.
