Audi TT 2000 Bulb Size
Bulb size chart
This page helps you find the correct bulb sizes for the 2000 Audi TT by lighting position, so you can match each lamp to the right replacement before you buy. Because trim and lighting equipment can vary by market and body style, it is best to compare the bulb chart with the bulbs already installed in your car.
For the 2000 Audi TT, the chart includes common exterior and interior locations such as low beam headlights, fog lights, parking lights, turn signals, brake lights, reverse lights, license plate lights, dome lights, map lights, glove box lights, and cargo area lights. Use the position name first, then confirm the bulb type listed for that specific socket.
Fitment can differ depending on trim package, lighting option, and whether your TT has halogen or HID headlights. That matters most for the low beam bulb, since halogen cars use H1 while HID-equipped cars use D2S. Some owners also upgrade to aftermarket LED bulbs or conversion kits, but those changes may affect beam pattern, warning messages, or legal compliance. Before ordering, check the bulb currently installed in your 2000 Audi TT whenever possible, especially if the car has been modified or if you are unsure about the original equipment.
