Audi S6 2009 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2009 Audi S6 by lighting position, so you can match the correct bulb to the correct socket before you buy. Whether you are replacing an exterior lamp, a cargo light, or an interior courtesy bulb, checking the location first is the easiest way to avoid ordering the wrong part.
The 2009 Audi S6 uses a mix of HID, LED, and standard bulb types depending on the lamp position. Because fitment can vary by market, body style, and lighting package, this year page is organized to help you quickly identify the bulb size for each area of the car, from headlights and turn signals to license plate and dome lights.
For the best fit, compare your vehicle’s trim and lighting package with the bulb chart before purchasing. Some positions may use LED assemblies from the factory, while others use replaceable halogen-style bulbs or HID capsules, and aftermarket LED conversions may not fit or function the same way as original equipment. If you are unsure, remove the installed bulb and check the markings on it before ordering, since small differences in socket style, wattage, or bulb shape can matter even on the same model year.
