I think pigs react very differently to lights based on their experience. When I lived in Oklahoma, if you used a bow mounted light, either green or red, you had about a second to shoot after you turned on the light. After that, they were gone. Problem was I saw the same sounders over and over, and they had become educated to lights. Best bet was definitely using a feeder light and letting the hogs get comfortabe at the feeder before stalking in from a long way away. I killed a couple using a bow mounted light, but by far the exception to the rule. In other areas, they don't seem to mind hardly at all. Dendy Cromer kills tons of them stalking with the green light on in the fields in Georgia. They don't seem to mind. I still have a bunch of bow mounted lights just in case a hog is just outside the main beam of a feeder light and I can't see well enough for a shot.
