The 2020 Audi TT RS is a performance-focused coupe and roadster with a lighting setup that can vary by market, body style, and equipment package. This year page is designed to help you verify bulb sizes by lighting position, so you can match the correct bulb or LED assembly before ordering replacements.
For the 2020 TT RS, many exterior lighting positions are listed as LED, including the headlights, fog lights, daytime running lights, brake lights, turn signals, tail lights, license plate lights, and reverse lights. Interior and cargo-area lamps may use different bulb types, so checking each location separately is the best way to avoid a mismatch.
Fitment can change depending on trim, package, and regional specifications, so always compare the bulb position on your car with the listing on this page before buying. Some 2020 Audi TT RS models use factory LED lighting in many positions, while others may have different serviceable bulbs in certain interior areas or market-specific rear lighting. If you are considering an aftermarket LED conversion, make sure the replacement is compatible with the vehicle’s electrical system and does not trigger warning messages or flicker. The safest approach is to inspect the installed bulb or assembly first, especially for glove box, trunk, dome, map, and interior door lights, where the bulb type may differ from the exterior lighting setup.
