I've been wanting to get a set of black housed headlight housings to replace my "home cleared" ones. I found 2 types at
www.autodymic.com One is the basic black housing and the other is with an ION lens. Now the lense looks kinda cool in the picture but I was wondering what exactly it's purpose is? Does it change the color of the light beam or something? If so, what color? I am currently using the PIAA Platinum Hyperwhite bulbs if that helps.
Thanks for all the info.
