They come in various forms, such as fairy lights, LED strips, and themed lights for holidays or events. LED decorative lights are energy-efficient, long-lasting, and often available in a variety of colors and patterns, making them popular for both indoor and outdoor decoration. They can enhance the aesthetic of a room, garden, or event space, adding warmth and creativity.
