First: Whoever thinks that would shine ANY lamps or xenon blue blue, just because the glass has this color is quite often fallen on his head. This light here is very bright and very white. Clear it said that "Blue Vision", but I think I have heard time that the blue glass nothing else does to make it appear whiter than the light, because it is the herrausfiltert yellow. I use them as parking lights and am happy with it and did not expect that they glow blue, which I also did not want to. I can not say anything about the longevity.
