Re-use that useless 12VDC adapter near the cup holder and power some overhead lights with it!
These lights are bracketed to the Roll Over Protection System (ROPS) using two U-bolts and some custom hardware. The most interesting thing this video covers is how to get power to your lights. Here are the materials used in the video:


Front Light (Nilight - NI06A-72W 12Inch 72W)
Rear Lights (Nilight - 60001F-B Led Pods 2PCS 18W )
Electriduct 3/8" UV Rated Flame Retardant Wire Loom

MICTUNING MIC-B1002 LED Light Bar Wiring Harness, Fuse 40A Relay On-off Waterproof Switch (I used the switch and only two feet of the cable)
18gauge stranded wire
Zip ties
Electrical tape
Heat shrink tubing
2 x U-bolts
1/8" or 1/4" thick steel bar
A method to solder the wires together
