no, I mean install HID bulbs and ballasts into the 300 dollar ones. I have that done to my 500s and its AWESOME! Not just for desert racing trust me. they are better and brighter than with the 130w halogens I had in them before, the light color/etc is better as I used 4300k, no blue 6000k garbage, and best part, only half the draw on the electrical system. they are only 55w. I am not sure how they would behave with the KC lenses, but the 500s LOVE the hid bulbs, even beam pattern, not hot spots, not big light blobs etc. just great smooth light. you pay 300 bucks for the lights, then about 50-60 bucks per pair to install hid. Its simple and works for off road lighting. In your headlights, NOPE, in driving/spot etc lighting, YEP! They also work great in IPF 968s so I am guessing the KC would be the same. My hellas perform WAY better than those Chinese HID lights you see for sale on ebay. The Hellas were 78 bucks and my HID kit was 34 bucks. Great deal for insane lighting.
