We made a Glow In The Dark Light because it could be used as an emergency light if you don't have one all you need to do is turn on the switches then you got four LED lights shining to whatever you need. Some times you need to buy batteries but when you have four your probably not gonna need to buy batteries for a while. We made it so the LED lights reflect off some saran wrap so it could reflect to the object your trying to shine it on.
