2020 Audi S6 bulb fitment is LED for both the low-beam and high-beam headlights. The supplied data does not identify separate bulb codes or a projector/non-projector headlight variation, so verify the lamp assembly before ordering replacement parts.
- Front lighting is LED for the headlights, turn signals, cornering lights, daytime running lights, parking lights, and front side markers.
- Rear lighting is also LED, including the brake, center stop, tail, reverse, rear turn signal, and rear side-marker lights.
- License-plate, step, dome, map, reading, trunk, and vanity lights are listed as LED.
- For the glove-box and general interior lighting, the supplied fitment lists bulb types 2825 and 98.
- No fog-light bulb fitment is listed for this model year.
Because most exterior lighting is identified as LED rather than a replaceable halogen-style bulb, confirm the original component and connector when servicing a lamp.
