Hogs are smart. I have lights on some of my feeders, both green motion lights and one feeder with a medium wattage white light that gets a bit brighter with motion. Hogs get used to those lights coming on real fast for the treat of corn. I’ve shot a good number right out from under the feeders using only the motion lights. It’s better if you can set them up with the lights angled back toward the feeder and away from where you’ll be sitting (downwind and generally to the south) so the photocells get charged and the hogs are lit on the sides rather than just the head and back.
I have both red and green kill lights mounted on rifles. My hogs get spooky real quick if they’ve been hit with that light. But it’s enough to get the first few before they get wise. Not a few at one time but one this week and maybe another next week. If there are multiples around when you pop one it’s much more likely they’ll bolt next time they see the flashlight.
