I was initially going to go with the Greddy drl kit but opted for these instead.
Audi LED Strip Lights | LED Daytime Running Lights | LED Headlights
When I ordered them I ordered a quantity of 2 not knowing they were sold in pairs. Since I had and extra pair I figured i'd try something out. My window tint is dark, so dark that backing up is uhmmm interesting. Wanted to see what backup led's would look like. Not sure if I like them or not.
Install for both front and rears from start to finish was about 3 hours. The strips are much more affordable than the Greddy's and look great in the evening, though if you're looking for actual drl's they are insufficent in my opinion.
