The 2017 BMW M6 uses integrated LED bulbs for both the low-beam and high-beam headlights. The supplied fitment data does not list a separate halogen or HID headlight option, so confirm the original lighting assembly before ordering replacement parts.
Other exterior lighting is also LED-equipped, including the fog lights, front and rear turn signals, brake lights, center stop light, cornering lights, daytime running lights, parking lights, side markers, tail lights, and license plate lights. This means most exterior lamp replacements involve an LED assembly rather than a conventional replaceable bulb.
The main conventional exterior bulb listed is the 921 reverse light. Interior applications have several fitment options: the map light uses a 2886X bulb, while the glove box uses LED lighting. The interior and vanity lights may use either 2825 or 98 bulbs, and the trunk may use either 6411 or 6428. Check the installed bulb and socket style before purchasing, especially for these interior locations.
