Tom95 wasn't eluding to how much amps per foot of wiring, but that for the sake of doing it once, and doing it with more capacity and safety factor is the ideal choice.
That's a pretty chart, but for the for the sake of a few bucks on wire, and the ability to put more powerful lights onto the same wiring later it's not WRONG to go beefier.
I would never run 16ga wire on purpose just because a chart says I can.
It's a jeep, no sense in wimping out on the modifications
