Fairy lights are small, decorative lights often used for festive occasions or to create a cozy atmosphere. They typically consist of tiny bulbs strung together on a flexible wire, making them easy to shape and hang. Available in various colors and styles, fairy lights can be powered by batteries or plugged into an electrical outlet. These lights are popular for decorating homes, gardens, and events like weddings and parties. They can be used indoors or outdoors, adding a magical touch to any space. Fairy lights are also energy-efficient, with many options using LED technology for longer-lasting illumination.
