Is it legal to use a light on your sight in Illinois?

YES IT IS LEGAL

have you used it yet.i used one this season.and it sure works great .good luck

No I haven't used one yet. I just bought a Copper John and don't think the pics are the brightest plus I bought a Double Bull and figured it would get pretty dark in there early morning and late afternoon and though it would be a good idea to get a light as long as it was legal.
