Neon signage refers to illuminated signs made using glass tubes filled with neon gas or other gases. When an electric current passes through the gas, it emits a bright, colorful glow. These signs are often used for advertising and decoration, attracting attention with their vibrant colors and unique designs. The use of neon signage dates back to the early 20th century, becoming popular in the 1920s and 1930s. They are commonly found in urban areas, especially in restaurants, bars, and theaters, where they enhance the visual appeal and create a lively atmosphere.
