Audi Q7 2020 Bulb Size
Bulb size chart
The 2020 Audi Q7 uses a mix of LED, HID, and halogen-style service bulbs depending on the lighting package and market, so the safest way to shop is by checking each bulb position individually. This page is designed to help you verify bulb sizes by lighting position, making it easier to match the correct replacement for headlights, taillights, interior lights, and other exterior lamps.
If you are replacing a failed bulb on a 2020 Audi Q7, start with the exact lamp location rather than assuming all trims use the same part. Audi offered different headlight and signal configurations on this model year, and the bulb chart on this page separates those fitments so you can compare your vehicle before ordering.
Fitment on the 2020 Audi Q7 can vary by trim, lighting package, body style, and market, so always confirm what is actually installed on your vehicle before buying replacements. Some Q7s use full LED lighting, while others may have HID headlamps or different rear signal and marker bulb setups. If you are considering an aftermarket conversion, make sure the bulb type, connector, and housing are compatible, since swapping to LED or HID parts is not always plug-and-play. For the most reliable result, inspect the bulb currently in the vehicle and compare it with the chart before purchase, especially for exterior lights and any lamps tied to driver-assist or lighting control systems.
