You can buy all the parts for the lights, on/ off switch and fuse from Radio Shack pretty cheap. Mount it all to a scrap piece of aluminum. Cost, around $30.00 and a little time to solder it all up. I have a wiring diagram that Gil sent me. He was selling them for $75. The costly part is the 6 pin plate from USLC. Dan H. was working on making them. Not sure if he ever got it done. As Gimpster suggested, perhaps the original neutral plate can be modified.
