Have you seen those lights you stick on a wall or in your closet?
 

Seen them advertised on TV. They are lamps that you can put in a closet, or line your stairway with them. Don't need to be wired to anything, just tap them and they go on.

Anyone know what they are called?

QUIK BRITE . . . doesn't look like what I am talking about, but seems to do about the same . . . these were more oval.

found them . . .never mind
