The Automatic On-Off Smart Nightlights have built-in photoelectric sensors that turn the bulb on automatically when dark and shut it off when bright. Working from dusk to dawn, they swivel 360 degrees to illuminate dim hallways, stairs, bedrooms, basements - anywhere light is needed. Simply plug in to an outlet and rotate in any direction to light the path - the wall, the floor - even the ceiling.Find the NIGHT LIGHT LED WHT 2PK at Ace.
