This one is pretty cool, replaces outlet cover and adds 3 LED lights pointing down.

This does look cool. But knowing little about outlet sockets, I'm a somewhat hesitant about how this connects to the wires and screws of the outlet box. I guess it must be UL certified in order for the company to sell it in US.
