Neon Indicator Lamps

Neon indicator lamps (also called pilot lights) are lights used on some electrical equipment to indicate that electrical power is available or that the device is working. Light-emitting diodes (LEDs) are often used as an alternative. They generally have a long life, low current drain and are resistant to shock and vibration.

How do neon indicator lamps work?

Neon indicator lamps are designed with two electrodes within a small glass case. Two tin plated wires extend out of the lamp to make electrical connections to the electrodes. These lamps are filled with either a neon and argon gas mixture, with neon gas used entirely for high brightness lamps. When a voltage is applied, the gas ionizes, allowing a small current to travel from one electrode to the other. Once this has happened, a lower voltage maintains the operation of the lamp.

What are the different types of neon indicator lamps?

Neon indicator lamps are designed in different colours and with varying brightness levels. They are available in different lengths, voltages and current ratings.
