Set of 2 LED Outlet Covers - Nightlights
Using a built-in sensor this outlet cover automatically turns on a LED when it's dark, and switches off when a room is bright enough again
It's ok to sacrifice an outlet to a nightlight in a child's room to scare away monsters, but elsewhere in your home they're far more valuable for other electronics and appliances. And that's exactly why these replacement outlet covers with built-in LED nightlights are so clever—and should eventually be standard in every home.
They can be installed on most outlets without needing any wiring
