Wrong, you do have to cut some of the housing. The back if the headlight is too long so you have to cut off tue part of the headlight that the stock bulb fits onto, and you have to cut the shroud to fit. Also, the mini h1 ALREADY HAS CLEAR LENSES! You don't need to order them!
I'm working on making a how to on these now. Hopefully I'll have it done in a week or two.
