A few months ago, I began accumulating parts to do a major rehab of my '06 Wee. One project is to convert to HID headlights. I bought a kit from HID Nation that is a Xenon lo-beam/halogen-hi. Wish I would have opted for a bi-xenon instead. I opted for the digital ballast with my kit and here is where I am having issues. This kit appears to be a good quality one, but it is VERY bulky and I am having trouble trying to get all of the components inside the area where the headlight are mounted. The original H4 halogens had no ballasts so they take up very little room, but this kit is driving me nuts trying to get it mounted so that it doesn't interfere with the steering. I thought I was being slick by mounting the ballasts to the side of the steering tube but they are a tad thick which causes the fork tube to hit them on the left side. Nice kit but mounting will take planning and beau coup patience. I'll get it eventually.
