2018 BMW M5 bulb fitment is LED throughout the supplied fitment data. Both the low-beam and high-beam headlights use LED lighting, so no halogen bulb size is listed for either position. The fog lights and daytime running lights are also LED.
Exterior lighting is specified as LED for the front and rear turn signals, brake lights, center stop light, tail lights, reverse light, parking light, and both front and rear side markers. The license plate and step lights are LED as well.
- Headlights: LED low beam and LED high beam
- Fog and daytime lighting: LED fog lights and LED daytime running lights
- Rear lighting: LED brake, center stop, tail, reverse, and rear turn signal lights
- Interior lighting: LED dome, map, glove box, trunk, vanity, and other interior lights
The supplied data does not identify separate projector or non-projector headlight variations, nor does it provide replaceable bulb codes. Verify the original lamp assembly before ordering a replacement or retrofit.
