This 2020 Audi A6 bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. The A6 uses a mix of LED and halogen lighting depending on the lamp location, and some exterior items can vary by trim, package, and market.
Use this page as a quick reference for the 2020 Audi A6 when replacing exterior and interior bulbs. It covers common fitment points such as headlights, brake lights, turn signals, license plate lights, map lights, and cargo-area lighting, making it easier to identify the right bulb for each spot.
Fitment on the 2020 Audi A6 can change with trim level, lighting package, body style, and regional equipment, so always compare your vehicle with the bulb position listed here before ordering. Some lamps are factory LED units, while others may use halogen bulbs such as D3S, H15, H7, or H11 depending on the configuration. If you are considering aftermarket LED conversions, make sure the bulb type, connector, and housing design are compatible, and keep in mind that not every retrofit will work correctly in every reflector or projector setup. The safest approach is to check the bulb already installed in your car, confirm the socket style, and verify the lamp function before purchasing replacements.
