For the 2013 Audi A7, the listed headlight fitment uses a D3S bulb for both low beam and high beam. Confirm the existing headlight setup before ordering, since the supplied fitment data does not list a separate halogen or projector-specific alternative.
The front turn signals use 5200 bulbs, while the reverse lights use 921 bulbs. With HID headlights, the cornering light is listed as an H8 LED; this condition is important when checking the front lighting configuration. The supplied data does not list a fog-light bulb for this model year.
- Front and rear side markers: 2825
- Courtesy, glove box, interior, and trunk lights: 2825
- Dome light: 6411
- Vanity light: 6418
For the main headlights, match the replacement to the D3S specification for both beams. If the vehicle has HID headlights, verify the cornering-light configuration as well, because the listed H8 LED application is conditional on that equipment.
