It worked great, I kept the 12v sla battery, bought the cheapest set of lights and ballast kit on Ebay. I went with a 35 watt HID headlight bulb to have longer run time even with the large old style ballast it still fit into the cavity of the Thor. I picked up a second cyclops at a fleamarket and slipped in H4 4500LM COB LED Bulb Hi/Low Beam Motorcycle Headlight bulb 6000K from ebay. It worked ok but gets hotter than a led should, the ad says 18 watts low and 40 high but I measured only
about 8 low and 19 High, I like it better than the HID because it's great for quick use, however the HID is much brighter and I will always turn to it anytime I will have the light of for more than a minute or two.
