Need emergency lights?  If you have a business, even a small business, then you need to have an exit sign.  I think businesses are supposed to have them over every exit, which I think is a great idea.  If there really is an emergency, most people are not in “thinking” mode but are in “panic” mode.  An easy to read sign doesn’t require any thinking but guides people to where they can go out of the building.

(Some moms might want one of these signs for the friends of their teenager.  Just kidding!)
