This 2003 Audi TT bulb size guide is designed to help you verify the correct bulbs by lighting position, so you can match each exterior and interior lamp to the right fit before you buy. Because the TT could be equipped with different lighting packages, the exact bulb type may vary by trim, market, and body style.
Use this page as a quick reference for common replacement bulbs on the 2003 Audi TT, including headlights, parking lights, turn signals, brake lights, reverse lights, license plate lights, and interior bulbs. Checking the bulb location first is the easiest way to avoid ordering the wrong part.
For best results, confirm whether your TT has halogen or HID low beams before purchasing headlight bulbs, since the listed fitment differs between those setups. Trim and package differences can also affect items like fog lights, dome lights, and courtesy lighting, and some aftermarket conversions may change the bulb type from factory specification. If you are replacing a burned-out bulb, it is smart to remove the installed bulb and compare it before ordering, especially on a 2003 model where previous repairs or upgrades may already have altered the original fitment.
