Audi TT RS 2019 Bulb Size
Bulb size chart
This page covers the 2019 Audi TT RS and helps you verify bulb sizes by lighting position, so you can match the correct replacement to the right lamp on the car. Because lighting can vary by market, trim, and equipment package, it is best to confirm the specific location before ordering.
For the 2019 TT RS, many exterior and interior lighting points use LED assemblies, while a few interior utility lights use 2825-style bulbs. This makes position-based identification especially useful when you are checking headlights, tail lights, turn signals, license plate lights, or cabin lights on the same vehicle.
Fitment can differ between trims, regional specifications, and lighting packages, so do not assume every 2019 Audi TT RS uses the same bulb setup. Some cars may have factory LED units where others in a different market may be configured differently, and aftermarket conversions can also change what is installed. If you are replacing a bulb, check the existing bulb or lamp assembly before buying, especially for interior lights and any part that may have been upgraded from halogen to LED. When in doubt, compare the installed bulb, connector style, and housing shape to the listing details to avoid ordering the wrong part.
