Neon signs

Neon signs are illuminated displays created using neon gas enclosed in glass tubes, which emit a bright, colorful light when an electric current passes through. The electric current excites the neon atoms, causing them to glow with a characteristic reddish-orange hue. By using different gases or coatings inside the tubes, a variety of colors can be produced. Neon signs are commonly used for advertising and decorative purposes because of their vibrant visibility and distinctive glow, especially at night. The technology dates back to the early 20th century and remains popular for its striking visual appeal.
