I'm very happy with a pair of 18 watt LEDs, one facing forward, one rearward, under the ROPS. They're wired from that auxiliary wiring in the left rear harness, through a fuzed toggle switch mounted on the lower part of the left rear ROPS.
I was going to mount a second pair, so I had two front, two rear, but I find that a single bright white 18 watt does the job for snow plowing; and if I *had* to do an extended period of nighttime backhoe work, I could just loosen the mount and flip the second one to the rear.
Don't forget you have a 12v plug by your feet you could use, too. Handheld floodlight could be plugged in there and taped or zip-tied in place on the ROPS for a temporary need.
