For the 2020 BMW X6, headlight bulb fitment depends on the installed headlight system. Models with HID headlights use D1S bulbs for both the low beam and high beam. Models with LED headlights use integrated LED lighting for both functions. The fitment data also lists LED for the high and low beams generally, so verify the headlight type before ordering.
Other exterior lighting is primarily LED, including the fog lights, daytime running lights, brake and tail lights, reverse lights, front and rear turn signals, parking lights, side markers, and license plate lights. For the front turn signal, HID-equipped models use a 5200 bulb, while LED-headlight models use LED lighting.
Interior lighting is also listed as LED in the dome, map, glove box, vanity, and general interior locations. The trunk light may use either a 2825 or 98 bulb, so check the existing bulb or socket before replacement.
