For the 2022 Audi Q7, headlight bulb fitment depends on the installed headlight system. Models with HID headlights use D5S bulbs for both the low-beam and high-beam applications. Models with LED headlights use LED lighting for both beams. The fitment data also lists LED for the high beam and low beam without a condition, so confirm the headlight type and existing housing before ordering a replacement.
