The Audi TT is a sports car that has been in production since 1998. It’s currently in its third generation. When it comes to headlights, Audi offers three versions of the TT that feature LED technology. The top trim boasts of Matrix LED headlights that illuminate the road intelligently.

Bulb types used in headlights

The Audi TT uses the H7 bulb for its low beam and high beam headlamps. For its fog lights, it uses the H11 bulb. This is, especially, for 2006, 2007, 2008, 2009 model years.

Upgrading from factory bulbs to aftermarket LED/HID

When upgrading your headlight bulbs, it’s important to note that direct-replacement units may not exist. This means that your new bulb may interact differently with the headlight housing and produce light differently. This may be a bigger issue where reflector assemblies are used to replace projector headlights.

Advantages of upgrading headlights from halogen to LED/HID

  1. Prolongs the lifespan of your headlights.
  2. Improves on-road visibility, hence, improved safety.
  3. LEDs and HIDs save energy by consuming less power.
  4. LEDs and HIDs are relatively inexpensive.
  5. They also provide a larger spectrum of visibility.

How to choose the correct bulb size for your LED/HID lamp

To determine the correct bulb size for your LED or HID lamps, you can either take a look at your old bulbs for their size/part number, consult your vehicle’s manual, or call your vehicle dealership or manufacturer. The last method may require you to share your vehicle’s VIN. This should be indicated on your dashboard, door panel or on somewhere on the driver’s seat.

If these options do not work for you, you can try checking out our Audi TT light bulb replacement chart below. There are large databases that include a list of the bulb sizes and types appropriate for each Audi TT generation. All you need to do is to choose your vehicle type together with its year of manufacture.

Installing new bulbs

The process of installing new bulbs on an Audi TT is long and tedious.

  1. Open the hood of your car.
  2. Remove the power connectors from the back of the headlight.
  3. Remove the old bulb and replace it with a new one.
  4. Reinstall the bulb into the headlight assembly and reconnect the power cables.  
  5. Test your new bulbs to see if they work. 

Additional equipment

When installing HID headlights, you may be required to wire a ballast that holds the bulb in place. This is normally an easy process to carry out but may result in a poor beam pattern if done wrong. In some scenarios, it may leave the car blinding other drivers or preventing the driver from seeing clearly at night.

What is a Headlight Aiming Wall Screen?

The wall screen is a method used to improve the aiming of headlights. It requires a flat, long working bay. The method is currently outdated for it consumes a lot of time and is not practical for most repair applications.
