I've found that the distance range isn't amazing on mine, but the lit areas on the road in front of me are all strongly lit with very little fade towards the outer edges. I wonder how the LED headlights that Audi and Seat can spec compare with Xenons.
Suppose there is a little of what you were used to before that comes into this as my previous experience was standard lights that were really poor. As someone described better than me in being no more than candles to the night.
So these Xenon to me are a major uplift and the dynamic and cornering lights both do their jobs really well and something take as the normal now though.
Distance Range is not amazing though as you state and you cannot adjust them like would in past, but what is lit is bright and clear and once used to the distance limits you drive to them.
Maybe due to brightness the distance limit has had to be reduced to stop blinding oncoming drivers?
Seen the LED on road now and they look really bright as come towards you but be interested to see how much brighter they are? and if distance is compromised as a result.
So for me there is a huge difference
One thing have noticed is they must get pretty hot as no matter the wash jet you are left with a thin layer of baked on dirt around lamp centers that go a little yellowy if left.
