For the 2011 BMW X6, both the low-beam and high-beam headlights use D1S bulbs. Check the existing bulb and headlamp assembly before ordering, especially if replacing an HID component.
The front fog light is listed with two options: H11 LED or H16 LED. Use the option that matches your vehicle’s original fog-light socket and housing. Other exterior fitments include a 5200 front turn signal bulb, 64136 reverse and rear turn-signal bulbs, and a 7506R brake-light bulb. The center stop light and tail lights are listed as LED.
For smaller exterior and interior lamps, the X6 uses 2827 for the parking light and front side marker, 6418 for the license plate, and 2886X for the dome, map, and trunk lights. Step lights may use 2825 or 98. Courtesy-light fitment requires comparing the original: options are 2825/98 or 6411/6428.
