2013 Audi S8 bulb fitment
The 2013 Audi S8 uses factory LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not identify a separate halogen, HID, projector, or non-projector headlight variation, so no replacement bulb size is listed for either beam. The 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 are also listed as LED.
- Low beam: LED
- High beam: LED
- Reverse light: 921
- Glove box and trunk: 2825 or 98
For the reverse light, use a 921-size replacement. The glove-box and trunk locations show two listed options, 2825 and 98; verify the installed bulb before ordering. This fitment information does not list a bulb for the fog light.
