Sensor Dusk to Dawn: Point the tiny hole in the candle's body toward a window, and the built-in light sensor will detect changes in light, automatically turning the candle on at dusk and off at dawn. These electric window candles illuminate your window throughout the night without any manual operation or setup. Convenient Suction Cups: Each LED window candle comes with a strong suction cup, allowing secure installation directly on glass surfaces instead of using a sill holder. This design helps prevent accidental tipping or curtain interference, making it ideal for French windows or narrow sills. Ensure both the suction cup and glass surface are clean and flat for optimal adhesion. 7-Inch Roman Column Design: Ivory-toned taper candles feature a flickering 3D flame effect that creates a realistic glowing ambiance. Powered by 2 AA batteries (not included), each candle can operate for over 30 days. Suitable for standalone use or with candle holders, these flameless candles add a warm, natural touch to any space. Flickering Candle Flame: The 3D solid LED bead produces a consistent flame effect visible from all angles. The dynamic flicker mimics real candlelight and is bright enough to be seen from across the street, while eliminating risks of fire, smoke, or burns. Safe for use around children and pets. Package and Service: Each package includes 6 candlesticks and 6 suction cups. Every battery-powered window candle is thoroughly tested before shipment. Avoid use in high-temperature or high-humidity environments. For any issues during use, contact the Customer Support Team for assistance.
