Using these fairy lights is super easy. First, find a place you want to decorate, like a room or a garden. Connect the male and female JST connectors to power them up. They're great for adding a warm and colorful glow to any space. When it comes to safety, keep them away from sharp objects to avoid damaging the insulation. Also, don't submerge them in water even though they're IP65 waterproof; they're designed to resist splashes, not full immersion. For maintenance, just wipe them gently with a dry cloth if they get dirty. Store them in a cool, dry place when not in use to make them last longer.
