I have blue visions. Good, bright lights.. Not very blue though, even the completely blue side-lights you get with it aren't very blue. Look good though in the daylight when you look at your lights and see blue bulbs though lol.
I had a problem when I orginally fitted them, the adjustment was wrong and people kept flashing me all the time, probably thinking it was on high beam or something, so just make sure you adjust them correctly when they are being fitted.
