Audi S8 2013 Bulb Size
Bulb size chart
This 2013 Audi S8 bulb size page is designed to help you verify the correct bulbs by lighting position, so you can replace the right lamp without guesswork. Whether you are checking the headlights, brake lights, turn signals, or interior lights, the goal is to make fitment easier for the exact area that needs attention.
The 2013 Audi S8 uses LED lighting in many exterior positions, with a few conventional bulb listings for select interior and reverse light applications. Because lighting equipment can vary by market, trim, and body style, it is smart to confirm the bulb type for your specific car before ordering replacements.
For best results, compare the bulb chart with what is actually installed on your vehicle, especially if your S8 has a different lighting package or has had prior repairs. Some cars may use different assemblies depending on market or equipment level, and aftermarket conversions can change the original bulb setup. If a lamp has been upgraded from halogen to LED, or from LED to another style, the part listed on the chart may not match what is currently in the housing. Checking the existing bulb before purchase is the safest way to avoid returns and ensure proper fitment.
