Turn On a Bright Idea Motion sensor path lights illuminate the way to energy savings. Most solar-powered outdoor lights waste energy by staying on all night — at least until the battery runs out. Here’s a great way to lower the drain on your batteries allowing for nighttime illumination when and where you need it — our new Motion Sensor Solar Path Lights set. Unlike many typical solar-powered path lights, these lights turn on only when the motion sensor is triggered. Not only do these long-lasting lights save on battery usage and provide a well-lit path to welcome you home and welcome visitors to your door, but they cut down on unnecessary light pollution: something homeowners and cabin dwellers alike can appreciate, especially when enjoying the night sky.
