I replaced my fogs with HIDs from xenon depot. I used the 4300 K Volt kit. I removed the bumper which was pretty easy. To install I cut the old pig tails off and soldered the correct ones on. When I get on a computer I will check it out for the correct pig tail. Instal was simple I over complicated it for myself but figured it out on the end. The lights are so bright I can't remember last time I used the highs. No problems with them blinding on coming drivers at all. Over all very happy with them.
