I love my LED's. Had Xenon's on a TT before the S3 and the LED's cover such a long distance. As said above, the front indicators are so bright, you can see them reflecting on signs quite far ahead. The front fog lights illuminating when turning the steering wheel is a really cool and useful feature, especially here in Wales where there's rock and pot holes!
The brightness is immense and everything looks so clear. The only comment I do have is that the dipped bean could be a little further, maybe it can be adjusted?
In my opinion, the LED headlight unit looks better and gives it a more 'mean' look.
They look pretty snazzy when unlocking and locking too...
