Motion-activated: Worried about tripping in the dark every night? These lights automatically turn on when they detect movement. Perfect as a nightlight for stairs, steps, hallways, closets, and wardrobes. Energy-saving: They don't turn on during the day or when the surrounding area is bright to save energy. These sensor lights also automatically turn off after 15-20 seconds of inactivity. Sticks anywhere: Comes with super-strong double-sided adhesive pads to stick them anywhere. The built-in magnet also allows you to attach them to metal surfaces. These lights can be used wherever you want. Specifications: Each light is 7.6 cm wide and 1.8 cm thick, and contains 6 LEDs. The detection range is up to 2.4 m. Stays on for 15 seconds after activation. (Note: Do not place these lights too close together, as this will trigger the light sensor and only one of them will light up.)
