I bought these daytime running lights, because my round optics for my Audi A3 8L is better liked than the long LED bars. Unfortunately, I realized that the lamps + the necessary, additional support would obstruct the air intake for the intercooler my TDI`s. That's why I returned the lamps and yet bought instead the LED bars.
So to all TDI owners looking for in advance if you do not make the intercooler. For me "power loss for light" is not an option.
