Turns ON/OFF By Itself: Look, we’re all busy. We get home from a long day of work but it doesn’t stop. Kids, pets, spouse, cooking dinner, etc. It’s easy to forget you took 20 seconds to install a beautiful solar light. But no worries, Colorize turns on by itself. The built-in sensors know when it’s dark and it activates Colorize automatically. No need to fumble with a light switch or go outside to turn them on. Just look out your window and enjoy the light show.
