For the 2020 BMW M4, both the low-beam and high-beam headlights use integrated LED lighting. The supplied fitment data does not identify separate bulb numbers or a projector/non-projector variation, so confirm the complete headlamp assembly before ordering a replacement.
Other exterior lighting is also listed as LED, including the fog lights, front and rear turn signals, daytime running lights, cornering lights, parking lights, side markers, tail lights, brake lights, center stop light, reverse lights, and license-plate light. This means these applications are not matched to conventional replaceable bulb codes in the supplied data.
Interior lighting is primarily LED as well, covering the dome, map, trunk, and general interior lights. The glove-box light is listed with two possible bulb sizes, 2825 and 98, so verify the installed bulb or socket. The vanity light uses bulb 2723. Check the original bulb and vehicle socket where multiple fitments are shown.
