RE: Hunting hogs in Oklahoma
Not sure about the spotlight, but I'm pretty sure that you can with a depredation permit.
For the corn, I'll usually take one 40 pound bag and a gallon of diesel with me when I go hunting. I'm no expert, but I'd dig two or three holes, fill them halfway with corn and diesel and bury them. Then dig a small hole with a shovel, fill with corn and diesel and leave it exposed. Get the pigs to eat all of that, and then they'll be looking around for the rest. I've put corn out in the morning, and had the pigs come that night.
