The Motion Sensor Lights are a versatile and convenient way to add light in an efficient and cost-effective manner. When the switch is turned on, the 3-LED light turns on when movement is detected and stays on for 30 seconds after movement ceases. Requires 3AAA batteries (not included). Hook and loop tape is included and can be attached to a variety of surfaces or simply placed on a flat surface. Place it in the garage, RV, tool box, cabinet or locker.
