I had these also, and while they were super easy to fit, there were quality issues. One of the lights just filled with moisture when it rained. THQ informed me that this was normal for LED lights, and they would dry out. Which they did.... eventually... but then every time it rained - more water. So much so that algae started growing inside the light. In the end THQ gave me a full refund (thanks THQ) and I went back to the original VW lights. I've yet to find a replacement that I like.
