- Solar powered with USB charging option: The alarm system is powered by sunlight stored in efficient solar cells. After sufficient daytime sunlight, the flashing theft alarm operates in the dark and flashes every five seconds. You can also charge via the USB interface without installing the battery. - Easy, tool-free installation: Comes with adhesive stickers on the back. You can stick it to any smooth surface and install in seconds without tools or wires. It can be easily disassembled if needed. - Bright anti-theft flashing lamp: Equipped with high-brightness LED beads. When the light sensor detects darkness, the device flashes and stays on every five seconds. The LED car alarm light switch is built-in and not easily recognisable, so you need to use the prompts to turn it on or off. - Versatile protection for multiple locations: The flashing lamp can deter night theft not only for cars but also for motorcycles, caravans, houses, ships, and yards. It helps reduce the chances of theft. Use scenarios - Parked car at night: Place the device on a visible exterior surface to deter theft while away from home, using solar power to operate automatically after dark. - Outdoor vehicle or equipment: Attach to a motorcycle, caravan, boat, or other vehicle parked outdoors to provide a deterrent without wiring or battery installation. - Home, yard, or dock area: Mount on a shed, gate, or other property feature to help deter nighttime intrusion and protect valuables.
