Bulb size chart
This 2013 Audi A6 bulb size guide helps you quickly verify the correct bulb by lighting position, so you can match the right part before you buy. Because Audi used different headlight and trim combinations, the bulb chart for this year can change depending on the lighting package, body style, and market.
Use this page to identify the bulb type for exterior and interior lights on the 2013 Audi A6, including headlights, turn signals, brake lights, license plate lights, and cabin bulbs. Checking by position is the easiest way to avoid ordering the wrong replacement.
Fitment on the 2013 Audi A6 can vary a lot between halogen and LED-equipped cars, and some lamps use different bulb types depending on the package. If your A6 has halogen headlights, the bulb list is not the same as an LED-headlight car, so confirm the exact lighting setup before ordering. Aftermarket LED conversions can also change compatibility, especially for turn signals, DRLs, and fog lights, where error-free operation may require the correct bulb style or additional hardware. The safest approach is to check the bulb already installed in the vehicle, compare it with the chart by position, and verify the socket and connector before purchase.
