Quick Summary
A glow lamp is a type of electric discharge lamp used for indicators or night-lights. It contains a high-resistance filament within a small bulb. When a voltage is applied, the gas inside, typically neon or argon, emits a faint glow. These lamps are energy-efficient and long-lasting. Glow lamps can also function as voltage regulators because the glow discharge helps maintain a constant voltage across the lamp.12
