For the 2017 Audi Q5, both the low-beam and high-beam headlights use D3S bulbs. The supplied fitment data does not identify a separate projector or non-projector headlight variation, so confirm the existing bulb and headlamp assembly before ordering.
Fog-light fitment includes H11 LED, H16 LED, and 921 options. These alternatives may reflect different lamp configurations, so match the replacement to the bulb currently installed in your Q5.
- Reverse lights: 921
- Brake, center stop, daytime running, parking, tail, rear turn signal, front side marker, license plate, and step lights: LED assemblies
- Rear side marker: 2821
- Dome light: 6411 or 6428
- Glove-box light: 2821
- Map, reading, trunk, and interior lights: 2825 or 98
- Vanity light: 6418
Check the original bulb or fixture where multiple sizes are listed, particularly for fog and interior lighting.
