For the 2012 Audi A7, both the low-beam and high-beam headlights use D3S bulbs. This fitment applies to the listed headlight setup, so verify the existing bulb and housing before ordering.
The front turn signals use 5200 bulbs, while the reverse lights use 921. Vehicles equipped with HID headlights use an H8 LED bulb for the cornering light.
For exterior marker lighting, the front and rear side markers use 2825 bulbs. The same 2825 size is also listed for the courtesy, glove-box, interior, and trunk lights. The dome light uses 6411, and the vanity light uses 6418. Check the vehicle’s current bulb and socket when replacing smaller interior lamps, particularly if the lighting has been modified.
