First, I must say that I have "tested" already two other H15 "varieties" in blue execution with very bad experiences. At the first "variety" has the version not fit well and the Fernlich has shone in the trees !! Not to Fahrban. In the second "species" that was next to it, just not as bad. So as a high beam that could not call, and the focus was so bad that the light was just kind of scattered.
Here the Erfahung to this H15 XENON SPECTRUM BLUE Birenen: Very good, it is lit up on the road and very well focused. Bundled light beautiful, high beam. I was very bright then so pleased that I immediately bought a second set of it.
