Believe me, I already tried a 'kit' first. I actually tried 2 different brands in my 9006. Don't expect 'world class lighting'
Sorry if I'm sounding so negative, but I just want people to know not to expect to much (like BMW or Mercedes quality) from a kit that will replace halogen bulb using halogen optics still.
