This page helps you verify the bulb sizes for the 2010 Audi A6 by lighting position, so you can match the correct replacement to each exterior and interior lamp. Because fitment can change with trim, body style, and lighting package, it is best to confirm the bulb location before ordering.
Use the chart below to identify common bulbs on the 2010 Audi A6, including headlight-related lamps, rear signal and brake bulbs, license plate lights, and cabin bulbs. Whether you are replacing a single burned-out bulb or planning a full refresh, checking the exact position makes the job faster and helps avoid ordering the wrong part.
For the best fit, compare your A6’s equipment level with the bulb chart, since halogen and HID setups use different bulbs in some positions and market-specific trims may vary. Aftermarket LED conversions can also change brightness, color, and error behavior, so it is smart to verify compatibility before buying. If possible, remove the installed bulb and read the number on its base before purchase, especially for courtesy, interior, and exterior signal lights where several similar sizes may be used.
