At first I was against polish skeptical because the headlights were already so weak / weathered that I would have the TÜV no longer existed. Even though it's a bit annoying work (per searchlights approx 15 min), the result is convincing. The headlights look almost like new. At this price, in any case, a better alternative than the headlights exchange! There is also enough material to recycle yet another pair of searchlights. So with a clear conscience to be recommended.
