For the 2007 Audi S8, the supplied fitment data lists a D2S bulb for the low-beam headlight. No high-beam bulb size is provided, so check the existing bulb or vehicle documentation before ordering a high-beam replacement. The data also does not identify a projector or non-projector headlight variation, so this page should not be used to assume compatibility with a different headlamp assembly.
Other notable lighting information includes:
- Daytime running lights: 7506
- Reverse lights: 921
- License plate lights: 6418
- Parking and step lights: 2825 or 98
- Brake, center stop, tail, and rear turn signals: LED
Because several rear lighting functions are listed as LED, they may use integrated assemblies rather than replaceable conventional bulbs. Verify the original component and socket before purchasing, particularly for the parking and step-light positions where two bulb options are supplied.
