A neon sign is a type of sign or advertisement that uses glass tubes filled with neon or other noble gases such as argon or krypton. When energized, neon gas emits light in various colors and shapes. Utilizing this characteristic, store names, logos, and advertising messages can be displayed in fluorescent colors.
Neon signs emerged in the early 20th century and became very popular, especially in urban areas of the United States. They have become symbols not only of the cityscape at night but also in media such as films and photographs. Due to their unique shine and beauty, they are used in both retro or vintage settings and as accents in modern designs.
