1. Motion Sensor Lights: The motion activated LED lights are wireless and install quickly, easily, and neatly. Each motion sensor light indoor light strip is powered by 4 AAA batteries (not included). These kitchen undercounter lights easily attach/detach to the included magnetic strip for quick and easy battery replacement. The built-in daylight sensor will not turn on when it detects other light sources in the area, ensuring long battery life. To save battery life, do not install in high traffic areas. 2. Battery Powered Lights: Our closet LED lights use passive infrared technology (PIR) to detect human motion and turn on in dark or dim environments. These lights will not turn on if other lights in the room are on, this is to save battery life. These LED closet lights are motion activated and turn on within a 9-foot motion range at a 120-degree angle from the sensor. These motion sensor night lights do not have an on/off switch and can only be activated by a manually operated motion sensor. 3. Easy Installation: These closet light motion sensors include a magnetic strip with adhesive backing for easy peel and stick installation. The automatic lights for closets are attached to a magnetic strip to allow for easy removal and replacement of the batteries. No tools, screws, or nuts are required to install these battery powered lights, and they can be easily mounted on any dry, clean, and flat surface. IMPORTANT: Before applying the wallpaper peel and stick magnetic strips, clean the area thoroughly with a dry cloth to ensure a secure adhesion. For best results, test the light position before applying the sticky magnetic strips to the wall. 4. AND: Our battery powered wall lights are made of high quality materials that will not break, bend, or corrode over time. This motion sensor light is ideal for use in closets, pantries, hallways, bathrooms, drawers, attics, basements, rooms, cabinets, storage rooms, garages, storm cellars, vanity mirrors, workstations, and any other dark location.
