My wife drives her TT daily and every other winter she says that her back lights flicker or don’t work, each time it’s burnt the bulb holder, so had to replace it.
These new lights are LED’s so won’t get hot, so should last a lot longer. They also look much better than the original ones, and makes the car look younger with the modern design with the indicator lights.
Very easy to change, and she’s very happy with the look. (Double bonus)
