Audi TT 2023 Bulb Size
Bulb size chart
If you need bulb fitment help for the 2023 Audi TT, this page is designed to make the search easier by organizing bulbs by lighting position. Instead of guessing from a trim name alone, you can check the exact area on the car, such as the low beam, high beam, fog light, tail light, brake light, or interior lamps, and compare that location with the bulb type listed for this model year.
The 2023 Audi TT uses a mostly LED exterior lighting setup, with a few interior and cargo-area positions still using 2825-style bulbs. Because lighting equipment can vary by market, body style, and package, it is important to match the bulb to the specific position on the vehicle. This year page helps you confirm the right bulb category before you buy replacements.
For the best fitment results, always compare the bulb position on your car with the listing on this page and verify the installed bulb before ordering, especially if your TT has a different trim, lighting package, or market-specific configuration. Many exterior lights on the 2023 Audi TT are LED, which may mean the bulb is part of an integrated assembly rather than a simple replaceable lamp. If you are considering an aftermarket conversion, check whether the housing is designed for halogen or LED use, since mismatched conversions can cause fitment problems, warning messages, or uneven light output. Interior bulbs such as the glove box, trunk or cargo area, and interior door light use 2825 bulbs on this page, so those are the easiest places to confirm by removing the old bulb and matching it directly before purchase.
