Predators are one of the most common threats to chickens. Keep your coop safe with help from the ImPECKables Motion Sensor Animal Deterrent Solar Lights. These coop safety lights turn on at dusk to help ward off unwanted nighttime visitors. If a predator gets too close to your coop (within 20 ft.), the red LED lights will flash, creating a fire-like effect. It has been scientifically proven that warm-blooded animals are afraid of fire. When they detect fire or something similar to fire, they may escape from that range. As a result, the lights help drive predators away from your chicken coop. The lights are solar powered for low maintenance and are waterproof for durability in the elements. There are 2 chicken coop safety lights included per pack.
