So LED DRL's have been around for long enough for the trend to be picked up and many high end cars feature this Audi trend and why not? they look cool (mostly) and use less energy and are LED's so they never need to be changed out right?
So do 4 of every 10 cars i see with them have one burnt out or dead side? Seriously, I see it ALL THE TIME. They can't be cheap to replace the strip or, more likely, the controller. Its not one brand or another either, Jeep, MB, Audi, VW, etc. Are they all buying them from the same place?
On another note, this trend has officially reached the popularity level where knock off kits are all you find when Google searching for this.
