This motion-activated light is like having a guardian angel that safely lights your way. It has an advanced motion sensor that automatically turns on the light when it's dark and movement is detected. No more fumbling on a dark porch or stairs or in a dark closet. With a 360º swivel base and a pivoting head, you can point the light exactly where you need it. Battery operated – no expensive wiring or electricity needed. Just peel and stick anywhere you need light indoors or outside! Requires 4 "AA" batteries (sold separately). Plastic. Measures approx. 10 1/4"L x 7"W x 5"H.
