Glow Lamp

A glow lamp, also known as a neon lamp or indicator lamp, is a type of electric lamp that produces light by passing an electric current through a gas-filled tube. It consists of a glass envelope filled with a low-pressure gas, typically neon or argon, and a pair of electrodes at each end of the tube. When a voltage is applied across the electrodes, the gas inside the tube ionizes and emits light.

Glow lamps are commonly used as indicator lights in various applications, such as on/off indicators on electronic devices, power indicators on appliances, and warning lights on control panels. They are often characterized by their distinctive glowing appearance and are available in different colors.
