Neon lighting is a type of illumination created by using neon gas in glass tubes. When an electric current passes through the gas, it emits a bright, colorful glow. This effect can be achieved with other gases as well, producing different colors, but the term "neon" is commonly used to describe all such lights. These lights are often used in signage and decorative displays because of their vibrant colors and ability to attract attention. Neon lights can be shaped into various designs, making them popular for businesses, art installations, and nightlife venues.
