Personally, when I'm taking my side-by-side camping, hunting, or off on a long weekend's adventure, I like going in at night. It makes for a little harder camp setup, but you're not missing part of the following day. You're there, you're done, everything is ready to go once the sun comes up. But that means heading out in the inky blackness of the wilderness, where street lamps aren't a thing.
And while headlight technology for side-by-sides has come a long way from what could only be compared to old-fashioned gas lamps when they first hit the scene, accessory lighting is basically still required if you're going to see anything past 35 yards. Which you want to do, especially given the rutted out off-road trails with sharp edge drops that litter western trails.
Hell, even East Coast drivers benefit from them, as black bears and trees can sometimes jump out at you. And whitetail? Don't even get me started on how often folks hit those in the dark.
