Audi A6 2008 Bulb Size
Bulb size chart
This 2008 Audi A6 bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Whether you are changing a headlight, interior lamp, or rear signal bulb, checking the location on the car is the easiest way to avoid ordering the wrong size.
The 2008 Audi A6 used different bulbs depending on trim, market, and body style, so one A6 may not match another exactly. Use this page as a position-by-position reference for exterior and interior lighting, including common items like the license plate lights, map lights, brake lights, and reverse lights.
For the best fitment, compare your vehicle’s trim and lighting package against the bulb chart, especially if your A6 has halogen headlights, xenon/D2S low beams, or an aftermarket LED conversion. Some positions can vary by equipment level, and a bulb listed for one package may not be correct for another. Before placing an order, it is smart to remove the installed bulb and check the base style and markings, since previous repairs or non-OEM parts can change what is actually in the socket.
