The 2012 Audi A7 uses different bulb sizes depending on the lighting function, and some items can vary by market or equipment package. Use this guide to narrow down the right fit before you buy replacement bulbs for your A7.
Fitment on the 2012 Audi A7 can change with trim level, lighting package, body style, and whether the car has standard HID or adaptive HID headlights. That means one A7 may use a different cornering light setup than another, even for the same model year. If you are switching to aftermarket LED bulbs or converting from halogen-style replacements, make sure the bulb base, connector, and physical clearance all match the original housing. It is also smart to remove the installed bulb and compare it before ordering, especially for interior and exterior positions that may look similar but use different sizes. When in doubt, confirm the bulb already in the car and check the vehicle’s lighting package before purchase.
