Looking for the right bulb sizes for your 2005 Audi TT? This page is designed to help you verify bulb fitment by lighting position, so you can match the correct bulb to each exterior and interior lamp on the car. Because the TT could be equipped with different lighting setups, checking the bulb location is the safest way to avoid buying the wrong part.
For the 2005 Audi TT, bulb type can vary by trim, lighting package, market, and body style. That means the low beam, fog lights, and some interior lamps may not be the same on every car. Use the position-specific listings here to confirm the correct bulb before replacing anything, whether you are fixing a burned-out license plate light or refreshing the headlights.
Fitment can differ between halogen and HID headlight setups, and some cars may also have LED-related components in certain positions. If your TT has halogen headlights, the low beam bulb is listed as H1, while HID-equipped cars use D2S. Aftermarket conversions can change what is installed, so do not rely only on the original factory configuration if the car has been modified. The best practice is to check the bulb already installed in your vehicle, compare it with the chart, and then buy the replacement based on the actual bulb and housing you have in hand.
