What's the best way to set up some lights on my boxes for playing bags?

Question:I have made two boxes for playing bags. Most people around Chicago probably know what i'm talking about. Well now i was thinking to maybe set something up, like a light bulb connected to a battery or something so i can light it up during night play. Anyways i'm trying to figure out what's the best way to set this up. Thanks.

Answers:
light bulbs, batteries,boxes? your right, i am confused but what about lowes ? they have all sorts off lighting and should easily be able to help you with what you need rather cheaply !
