The 2018 Audi Q7 uses a mix of LED, HID, and standard bulb positions depending on the headlight package and market, so it is important to verify the exact lighting setup before ordering replacements. This page helps you confirm bulb sizes by lighting position, making it easier to match the correct bulb for the front, rear, and interior lights on your Q7.
If you are replacing a burned-out bulb or planning a maintenance refresh, the 2018 Audi Q7 bulb chart can save time and reduce guesswork. From headlight and daytime running light positions to license plate, cargo, dome, and mirror lights, the fitment details here are organized to help you find the right bulb for your specific configuration.
Fitment can vary by trim, lighting package, body style, and market, so always compare your vehicle’s installed bulb and housing before buying. Some 2018 Q7 models use LED lighting in many exterior positions, while others may use HID headlamps or different front turn signal hardware depending on the setup. If you are considering an aftermarket LED conversion, check for compatibility with the housing, warning messages, and beam pattern, since not every swap will perform the same as the factory bulb. The safest approach is to confirm the bulb type already installed in your vehicle and then match it before purchasing replacements.
The low beam bulb depends on the headlight package. Q7 models with LED headlights use LED low beam lighting, while models with HID headlights use a D5S bulb for the high and low beam setup.
High beam fitment also depends on the headlight type. With LED headlights, the high beam is LED. With HID headlights, the high and low beam function uses a D5S bulb arrangement.
