Swings when the wind blows, imitating real fireflies The most unique decorative solar lights on the market, our solar swing lights are supported by very soft and stretchable wires, so when the wind blows, the lights swing like a swarm of fireflies flying in the dark. Latest version - better swing effect The upgraded version uses a special iron wire and a resistance bulb base. The special iron wire has greater flexibility and can provide a larger swing angle. The resistor bulb base increases the oscillation pulse, allowing the sun's oscillation to better mimic a real firefly.
