Audi A6 2007 Bulb Size
Bulb size chart
This 2007 Audi A6 bulb size guide helps you verify the correct bulbs by lighting position, so you can replace only the lamp you need with confidence. Because Audi used different lighting setups across trims, body styles, and markets, the exact bulb in your A6 can vary depending on where it is installed.
Use this page as a quick reference for common exterior and interior bulb locations on the 2007 A6, including headlights, tail lights, reverse lights, license plate lights, dome lights, and small cabin lamps. Checking by position is the easiest way to avoid buying the wrong bulb when you are servicing a single light or planning a full refresh.
For best fitment, compare your vehicle’s trim and lighting package before ordering, since halogen and HID/xenon setups may use different bulbs and housings. Some owners also switch to LED replacements or aftermarket conversions, but those changes can affect brightness, color, warning messages, and beam pattern. If possible, remove the installed bulb and match the base and markings before purchase, especially for interior lamps and option-dependent cargo or trunk lights.
