The 2017 BMW X6 uses either D1S or LED lighting for the low-beam and high-beam headlights, depending on the factory headlight system. Confirm whether the vehicle has D1S/HID or LED headlights before ordering replacement parts. The fog lights are LED.
Front turn signal fitment also varies by headlight configuration: vehicles with HID headlights use a 5200 bulb, while vehicles with LED headlights use an LED unit. Most exterior lighting is LED, including the reverse, brake, center stop, daytime running, parking, license plate, side marker, tail, and rear turn signal lights.
Interior lighting is generally LED as well, including the dome, glove box, map, vanity, and other interior lamps. The trunk light is listed with either a 2825 or 98 bulb, so verify the existing lamp and housing before purchase.
