if you get a battery tender and keep the battery charged up, you can run the lights for a while during the night. maybe 2 or 4 hours and then you start getting flickering and stuff.
this Arctic Cat charging system is better than my Rhino and I ran the lights and gps and stereo.
I will be running the rugged radios also, with a rigid 40 inch and a 10 inch amber all on separate switches of course. I am starting with two batteries, it that doesn't work its a alternator.
It all adds weight and that is the enemy
