re: DIY red or green feeder lights for pigs

What's his price range? I wouldn't go too cheap on predator lights. A good Wicked Lights flood light is $260. I have never used one. If that's more have you looked into to just getting the mounted lights? If your only shooting 100 yards the wicked lights A48 is a great lightweight light. $140 and the kit comes with mount and an intensity corded control. Pigs typically look down and aren't affected as much by light as say a coyote. I've used cheap lights and there is a big difference if you spend a little more money. Same will probably be said for the Flood LED's if that's the route he wants to go.
