I have used Hella and weather he says they are crap I like them ! 85W and 100W makes the seeing much easy and brighter ! Also every single person who sat in my car told me " wow, you got Xenon lights ? " they did not know the type of the bulbs nor how much I paid for them ! I have 85W city (low) and 100W highway (high) bulbs and a they are white ! I knwo they are dangerous in the plastic housing, will do something about it soon! Maybe the solution is replace the bulbs to HID as the bimmer magazine reported it is possible , around 400USD/side. until the Piaa and Hella 85W super whites are much better then 65/55W standard yellow ones, no matter what he says !
