Neon light

Neon lights are a type of electric lamp that use neon gas inside a glass tube. When electricity flows through, it excites the neon atoms, causing them to emit a bright, colorful glow—most famously red-orange, but with different gases or coatings, they can produce various colors. These lights are energy-efficient, long-lasting, and visually striking, making them popular for signage and decorative purposes. The process relies on the principles of electrical ionization and gas excitation, creating the luminous effect seen in signage and artistic displays.
