Audi TT 2011 Bulb Size
Bulb size chart
The 2011 Audi TT uses a mix of bulb types depending on the lighting position, body style, and equipment level. This page is designed to help you verify the correct bulb size by location, so you can match the right part before you buy or replace anything.
If you are changing a headlight, tail light, interior lamp, or exterior marker on your 2011 Audi TT, checking the bulb chart by lighting position is the safest way to avoid ordering the wrong fit. The TT’s lighting setup can vary, so a position-by-position guide is especially useful.
Fitment can differ by trim, lighting package, market, and whether your TT has factory halogen or xenon-style lighting components, so always confirm what is actually installed on the car before purchasing. Aftermarket LED conversions may look appealing, but they do not always fit or function the same way as the original bulb type, especially for headlights, DRLs, and turn signals. If you are replacing a bulb, it is a good idea to remove the old one and compare it directly with the new part before installation. That simple check can help you avoid mismatched bases, incorrect brightness, or warning messages on the dash.
