Neon Indicating Light
A neon indicating light is a small gas-discharge lamp that uses neon gas to emit a characteristic orange-red glow when voltage is applied. Commonly used as a power indicator in switches, panels, and appliances due to its low power consumption, long life, and visibility. Typically operates with a series resistor to limit current. Works on AC or DC, usually at 90–120V. Known for reliability in industrial and household applications.
