Bulb size chart
This page helps you verify the bulb sizes for the 2010 Audi S6 by lighting position, so you can shop with more confidence and replace the correct lamp the first time. Because exterior and interior lighting can vary by market, body style, and package, it is always smart to match the bulb to the exact location on the car.
For the 2010 Audi S6, the listed bulb chart includes common service points such as the headlight low and high beam, daytime running lights, turn signals, brake lights, reverse lights, license plate lights, side markers, tail lights, the center high mount stop light, and stepwell lights. Use the position on the page to narrow down the correct fit before ordering replacements.
Fitment can differ between trim levels, lighting packages, and regional specifications, so the same 2010 Audi S6 may not use identical bulbs in every market or body style. Some positions are LED-based from the factory, while others use replaceable halogen-style bulbs, and aftermarket LED conversions may require different parts or additional compatibility checks. If you are unsure, compare the installed bulb and connector before buying, especially for items like the D2S headlight bulbs, 7507 turn signal bulbs, 921 reverse bulbs, 2825 or 98 stepwell bulbs, 6418 license plate bulbs, 1156A brake bulbs, and 2827 side marker bulbs.

What is the front turn signal bulb size on a 2010 Audi S6?
The front turn signal bulb is listed as 7507. Check both sides if you are replacing a pair, since one side may fail before the other.

The rear turn signal bulb is also listed as 7507 on this page. Verify the socket and bulb shape before ordering, especially if the car has been modified.
What size is the reverse light bulb?

What are the side marker bulb sizes?
Both the front and rear side marker bulbs are listed as 2827. If one side has failed, inspect the other side as well because they often age at a similar rate.
What bulb size is used for the license plate light?
The license plate light bulb is listed as 6418. This is a useful bulb to replace when the plate area looks dim or one side is out.
Does the 2010 Audi S6 use LED bulbs anywhere from the factory?
Yes, the chart shows LED for the center high mount stop light, tail light bulb, and daytime running light bulb. That means those positions may not use a simple replaceable halogen bulb in the same way as other locations.
What are the stepwell light bulb options?
The stepwell light bulb is listed as 2825, 98. That indicates the page includes more than one listed option for that position, so you should match the installed bulb and socket before purchasing.
Why does bulb fitment vary on the 2010 Audi S6?
Trim, lighting package, market, and body style can all affect bulb fitment. A sedan in one region may not match a car with a different lighting package in another region.
Should I check the installed bulb before buying a replacement?
Yes. Checking the installed bulb is one of the best ways to avoid a mismatch, especially on a vehicle like the 2010 Audi S6 where some lighting positions may differ by configuration.
Can I switch the 2010 Audi S6 to LED bulbs?
You can often use aftermarket LED replacements in some positions, but fitment, polarity, error messages, and beam pattern can be issues. For headlights and other critical lighting, make sure the conversion is compatible with the car and local regulations.
