Also have LEDs for reverse..and stop and turn signals as well. Tails are tinted, but reverse was left clear so it's pretty bright to look at. I got mine from superbrightleds, but could probably be found for less. I had a credit with them other stuff, so it only cost me $10 for both bulbs, er, modules..
Simple plug and play, much brighter too. I'm also looking into an auxillary system for more light when needed. White Knight has a real easy 7-pin hookup setup, but they still use halogen bulbs, only 110 watts total. I want more power than that, and preferably LEDs. Probably going to get a couple of lightbars for Christmas, hopefully..
