Neon lights are gas discharging lights used as light sources for indoor and outdoor illumination applications. They were first produced by Georges Claude, an eminent French chemist, in 1910. They became commercially available in the early 1920s.
A neon light consists of a cathode and anode, fixed one at each end of the tube. When electric current is passed through this glass tube containing neon gas, the potential between the anode and cathode causes the electrons in the gas to ionize and glow in a bright color.

Neon lights work on relatively high voltage. Unlike incandescent lights, they have no filaments and have a typical lifespan of 10,000 to 25,000 hours. These lights operate under a wide temperature range from -40°C to +150°C. They are least affected by mechanical shock or vibration.
Neon lights come in a wide range of brilliant eye-catching colors. These colors are produced by mixing neon gas with other gases, by coating fluorescent powders and by using colored glass tubes. Typical color produced by a neon light is bright reddish-orange. By using other ways to create new colors, neon lights can emit colors such as green, yellow and blue. For example, when argon gas is mixed with neon gas in a glass tube it will emit a blue-color light.
Small neon lamps are used as indicators in electronic equipments whereas larger lamps are used in signboards. Due to its long lifespan and low current consumption, they are good as nightlights. Nowadays, application of neon lights is devised in digital logic circuits, binary memories and frequency dividers.
Neon lights are used mainly by business firms for advertising purposes. They use neon lights in their banners and signboards for catching attention of the general public. They have a significant role in generating sales. Banners and signboards written in bright and brilliant colors of neon lights are really a dazzling way to attract business.
