Neon lights are bright glowing, filled with thin neon gas or other rare gases of the electrified glass tube or light bulb, is a cold cathode gas discharge lamp. The neon tube is a sealed glass tube with electrodes at both ends, which fills some low-pressure gas. The voltage of thousands of volts is applied to the electrode, and the gas in the ionization tube causes it to emit light. The color of light depends on the gas in the tube.
Neon lights are the transliteration of neon, a rare gas that emits a popular orange-red light, but other gases are used to produce other colors, such as hydrogen (red), Helium (pink), carbon dioxide (white), Mercury vapour (blue), and so on.
