2018 Audi RS 7 headlight fitment: The supplied data does not list a low-beam or high-beam bulb size for this model year. Because headlight equipment can vary by factory configuration, do not choose a replacement headlight bulb from an unverified chart. Confirm the existing bulb, headlamp assembly details, or the vehicle’s documentation before ordering.
The supplied fitment data also does not identify a front fog-light, turn-signal, or reverse-light bulb size. The listed interior applications use a 2825 bulb for both the glove-box light and interior lighting. Check the specific lamp location and compare the replacement with the bulb being removed, particularly if the vehicle has original or modified lighting equipment.
