Product description Why do the lights turn on for a second and then turn off? This is usually caused by the built-in Dusk-to-Dawn Sensor, not a product defect. The lights are designed to work automatically at night and stay off during daylight to save energy. Can the lights charge on cloudy or rainy days? Yes. The lights support dual charging with both solar power and USB backup charging. The solar panel charges the battery during the day, while the USB option allows you to recharge the lights when sunlight is limited, such as cloudy or rainy days. Do the lights come with a remote control? Yes. Selected models include a convenient remote control that allows you to turn the lights on or off, switch lighting modes, and adjust brightness without needing to access the solar panel directly.
