Rainy days come with low visibility and danger for pedestrians, especially at night. Fairy Umbrella has LED lights attached to the umbrella top and rim. The lights are powered by a energy saving, recyclable “water battery.” For children and elderlies, this is a good accessory, even for sunny days.
Water batteries are stored in the handle.
Water coming through the central pole to the handle can be used to generate power for water batteries
