I guess its up for interpretation by the wildlife officer but NC Regulations Digest says:
"It is unlawful to use any of the following in taking wild birds or animals:
-artificial lights (including laser sights),"
I know folks who use them, but without clarification from wildlife officials, I wouldn't use them. Also, they are not P&Y legal, If that matters to you. I think they are a good idea, especially in low light and they don't help you kill an animal, just see where your arrow hit...
