2021 Audi S6 bulb fitment uses LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not identify a separate replaceable headlight bulb code or list a low-beam/high-beam variation by projector or non-projector housing, so confirm the complete headlamp assembly before ordering a replacement.
- Front turn signals, daytime running lights, cornering lights, parking lights, and front side markers are listed as LED.
- Rear turn signals, tail lights, brake lights, the center stop light, reverse lights, and rear side markers are also listed as LED.
- License plate, step, dome, map, reading, trunk, and vanity lighting are listed as LED.
- For the glove box and other interior lighting, the supplied data lists bulb sizes 2825 and 98, in addition to LED applications.
No fog-light bulb fitment is provided in the supplied data. Because most listed exterior lamps are integrated LED units, verify the specific lamp location and assembly requirements before purchasing.
