Audi S8 2007 Bulb Size
Bulb size chart
This page covers the bulb sizes for the 2007 Audi S8 and is organized by lighting position so you can quickly verify the correct fitment before buying replacement bulbs. Whether you are changing a headlight, a rear signal, or a small exterior lamp, matching the bulb to the exact location helps avoid guesswork and returns.
The 2007 Audi S8 uses a mix of LED and conventional bulb types depending on the lamp position. Because lighting equipment can vary by market and body style, it is a good idea to compare the bulb chart with the bulb already installed in your car before ordering. That is especially helpful on a performance sedan like the S8, where factory equipment may differ across trims and package options.
For the best fitment results, check whether your car has the original halogen setup or a converted LED setup, since aftermarket changes can affect bulb choice and warning messages. Trim level, lighting package, and regional specifications can also change the bulb used in a given socket. If possible, remove the old bulb and confirm the number printed on it before purchase, especially for exterior lamps and any upgraded LED assemblies. This is the safest way to avoid mismatches when replacing bulbs on the 2007 Audi S8.
