This page covers the bulb sizes for the 2006 Audi TT and is organized by lighting position so you can quickly match the right bulb to the right socket. Whether you are replacing an exterior lamp or a small interior bulb, checking the location first helps avoid ordering the wrong part.
The 2006 Audi TT could be equipped with different lighting setups depending on trim, market, and body style, so the bulb chart is meant to help you verify fitment before you buy. Use it as a practical reference for headlights, tail lamps, license plate lights, cabin lights, and other common bulbs on this model.
For the best fit, compare the bulb type on this page with the bulb already installed in your car, especially if your TT has an optional lighting package or has been modified over time. Halogen and HID headlight systems use different low beam bulbs, and some owners may also switch to LED replacements or aftermarket conversion kits, which can change the required bulb style or adapter needs. If you are unsure, remove the old bulb and check the base and markings before ordering, since small differences in socket type can matter even when the light looks similar.
