Audi TT 2020 Bulb Size
Bulb size chart
The 2020 Audi TT uses a mix of LED exterior lighting and a few small incandescent interior bulbs, so the right replacement depends on the exact lighting position. This page helps you verify bulb sizes by location, making it easier to match the correct bulb for the headlight, tail light, interior, and other lighting points on your TT.
Because trim and lighting equipment can vary by market and body style, it is important to check the bulb chart for the specific area you are replacing. For the 2020 Audi TT, many exterior functions are listed as LED, while items such as the glove box, trunk or cargo area, and interior door light use 2825 bulbs.
Before buying replacements, confirm whether your TT has factory LED lighting or a halogen-style setup in the area you are servicing, since trim and package differences can change fitment. If you are considering an aftermarket LED conversion, make sure the bulb type, connector style, polarity, and physical clearance all match the housing. For the best results, compare the installed bulb to the chart on this page before ordering, especially for interior lights and any market-specific exterior positions.
