What are fairy lights arrange in circuit?

Fairy lights arranged in a circuit refer to a string of small, decorative lights that are wired together in a closed loop, allowing electricity to flow through them. Each light bulb in the circuit typically shares the same electrical path, so if one bulb goes out, it can affect the entire string unless it has a parallel design. These lights are commonly used for decorative purposes, especially during holidays or special events, to create a whimsical and warm atmosphere. They can be powered by batteries or plugged into an electrical outlet.
