These shiny delights come in warm yellow, bright white and multicolored. They are on a string of 20 LED lights with a solar power panel. No need to plug them to a wall outlet, just set them up during the day so that they recharge fully and you will almost forget all about it until they start glowing at night! They will stay on for 8 to 10 hours and disappear in daylight to recharge fully and light up at night again! Waterproof and Weatherproof, these are a perfect way to add holiday glow to your house and your garden.
