Audi S6 2008 Bulb Size
Bulb size chart
The 2008 Audi S6 uses several different bulb types depending on the lighting position, so the easiest way to shop is by matching the bulb to the exact location on the car. This page helps you verify bulb sizes by lighting position, including exterior lamps, interior lights, cargo-area lights, and the headlight system.
Because trim and lighting package can vary by market and body style, the same 2008 Audi S6 may use different bulbs in certain spots. Use the bulb chart below to confirm the correct fit before ordering replacements, especially for rear lamps, cabin lights, and the headlight assembly.
For best fitment, compare your installed bulb to the listing on this page before you buy. Some 2008 Audi S6 models may differ by trim, package, or region, and halogen versus HID-style lighting can change what is used in the headlight area. If you are converting to aftermarket LED bulbs, make sure the bulb base, polarity, and physical clearance are compatible, since some LED replacements may not fit or may trigger warnings. When possible, remove the old bulb and match it directly, especially for shared interior and cargo-area positions where more than one option may appear in the chart.
