For the 2015 Audi SQ5, both the low-beam and high-beam headlights use D3S bulbs. The supplied fitment data does not identify a projector or non-projector headlight distinction, so confirm the existing bulb marking before ordering.
Fog-light fitment is listed with several options: H11 LED, H16 LED, or 921. Because these choices may reflect different fog-light configurations, compare the original bulb and housing before replacement.
- Reverse lights use 921 bulbs.
- Brake, center stop, daytime running, parking, tail, front side-marker, rear turn-signal, license-plate, and step lights are listed as LED.
- The rear side-marker and glove-box lights use 2821.
- Dome-light options are 6411 and 6428; interior, map, reading, and trunk lights are listed as 2825 or 98.
- Vanity lights use 6418.
