Sensor Dusk to Dawn: Point the small hole in the candle's body toward a window, and the built-in light sensor will detect changes in ambient light, automatically turning the candle on at dusk and off at dawn. These electric window candles illuminate your windows throughout the night without requiring 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 traditional holders on window sills. This design helps prevent accidental knocks or curtain interference, making it ideal for French windows or narrow sills. For best results, ensure both the suction cup and glass surface are clean and flat.7-Inch Roman Column Design: Ivory-colored taper candles feature a flickering 3D flame effect that mimics a realistic burning flame. Powered by 2 AA batteries (not included), each candle can operate for over 30 days. Whether used alone or with candle holders, these flameless candles add a warm, natural ambiance to any space.Flickering Candle Flame: The 3D solid LED bead creates a consistent flame effect visible from all angles. The dynamic flicker mode produces a bright, lifelike glow that can be seen even from across the street. These flameless candles provide the look of real candles without the risks of fire, smoke, or burns, offering a safe option for homes with children or pets.Package and Service: Each package includes 6 candlesticks and 6 suction cups. Every battery-powered window candle is thoroughly tested before shipping. Avoid use in high-temperature or high-humidity environments.
