If you guys want lights for a few hours, and not doing a lot of night running you would be better off with a couple of lithium ion batteries or one big one. Depending on the light you could run anywhere from 2 to 6 hrs on a charge. Led will run longer than hid. I would not waste my money on a 35 watt peak stator for $120. I could buy a 5 ahr lithium ion battery and not deal with the flickering. They fit in the air box and it is pretty easy to build a battery tray for it.
