Check the game regs in your state and see if they can be hunted at night. About half the pigs I have killed have been between dark and midnight.
A little corn under a feeder with a red light prjected on it will work nicely. You will need a scope with an illuminated reticle.
I put an ATN nightvision scope on my AR and shot one a few weeks back, didnt recover it. I think I may have gut shot it and never could find it.
