Bulb size chart
This 2015 Audi S6 bulb size guide helps you verify the correct bulb by lighting position, so you can replace the right lamp the first time. Whether you are checking the headlights, interior lights, or rear signals, this page is organized to make fitment lookup easier for the 2015 Audi S6.
The 2015 Audi S6 uses LED lighting in many exterior positions, while a few service bulbs still use traditional sizes. Because equipment can vary by market, trim, and lighting package, it is smart to confirm the bulb type for each location before ordering replacements.
For the best fitment results, compare the bulb listed for your exact position with the bulb already installed in the car, especially if your S6 has a different trim, optional lighting package, or a prior aftermarket conversion. Some locations may be LED from the factory, while others may use halogen-style service bulbs or LED modules depending on equipment. If you are upgrading to LED aftermarket bulbs, make sure the base type, polarity, and physical clearance match the housing, and check for warning messages or flicker issues on vehicles with bulb monitoring. When in doubt, remove the old bulb and verify the marking before buying a replacement.
