I researched this quite extensively last season and have been stewing on it ever since. You have a few different options depending on how far you want to get into it, and how much money you want to through at it. Should be a few threads you can dig up if you search around. Musselmans sx and srx build threads along with his hid conversion threads are the first that come to mind. To summerise however; you can swap to the dual bulb headlight found on the later model sxr and srx sleds with your stock stator and run two 35watt bulbs... you need the gauge pod, headlight, windshield and upper harness and newer style gauges if your sled doesn't already have them. To do the same conversion with the brighter 70 watt bulbs or whatever come stock,you will need everything listed already plus the entire harness, newer flywheel/stator and have the pickup coil welded in your case. Additionally you can do the first dual bulb conversion with you're existing stock stator with hid bulbs, but you will need everything first listed with the addition of a hid conversion kit plus a battery to fire the Ballest. I've done some reaserching on batteryless hid, because I'm not interested in adding a battery but not really enough to make heads or tails of it. There is a company that puts kits together but they start at about $400 which is a little out of my budget. I'm most likely doing the swap this season to at least the dual 35 watt setup and have everything but the gauge pod...
