Audi A6 2002 Bulb Size
Bulb size chart
This page helps you find the correct bulb sizes for the 2002 Audi A6 by lighting position, so you can match the right part to the right lamp before you buy. Because fitment can change with trim, body style, and lighting package, it is best to use the bulb chart here as a position-by-position guide rather than assuming every A6 uses the same setup.
For the 2002 Audi A6, many exterior and interior locations use different bulb types, including D2S low beams, H1 high beams, 2825 and 6418 interior bulbs, and 7506 rear signal and reverse bulbs. Checking the bulb location first makes replacement faster and helps avoid ordering the wrong size for headlights, tail lamps, courtesy lights, or cargo-area lighting.
Before purchasing, compare the listed bulb size with the bulb already installed in your car, especially if your A6 has a different trim, market-specific equipment, or an optional lighting package. Some owners upgrade from halogen to LED, but aftermarket conversions may need adapters, resistors, or different housings to fit and function correctly. If your vehicle has been modified, the original bulb chart may not match every lamp exactly, so confirming the installed bulb is the safest step before ordering replacements.
