Pilot Lights

Pilot Lights: LED status indication for control panels and machinery

Pilot lights provide a quick visual indication of circuit or equipment status without adding complexity to the control panel. This range covers compact LED indicators through larger panel-mounted pilot lights, with options such as the 12mm 24V red LED pilot light for compact indication duties.

Who Uses This

Pilot lights are commonly specified for industrial control panels, machinery, switchboards and automation equipment where operators need immediate visual feedback. They suit panel upgrades, machine builds and maintenance work where panel space, circuit voltage and indication method all need to be considered. Push-test and dual-colour configurations are particularly useful where the indication needs to provide more than a simple on/off visual signal.

Pilot Lights — Common Questions

How do I choose the correct pilot light voltage?

Match the pilot light voltage to the actual control or indication circuit rather than selecting by panel size alone. The range includes lower-voltage options such as 24V and wider 12–130V AC/DC designs, as well as 120V and 240V AC choices. For example, the 18mm 240V AC green LED pilot light is suited to a circuit requiring that specific operating voltage.

When is a push-to-test pilot light useful?

Push-to-test functionality allows the indication circuit to be checked without relying solely on the normal operating condition. It can be useful during commissioning, maintenance and fault-finding on machinery and control panels. A 30mm red push-to-test LED pilot light provides this function across a broad 12–130V AC/DC range.

What panel size should I choose for a pilot light?

Choose a mounting size that matches the panel layout, available space and the physical hardware used for the installation. Compact 12mm and 18mm indicators suit applications where panel real estate is limited, while 22mm and 30mm pilot lights provide larger, easy-to-see indication formats. The required cutout and mounting arrangement should always be confirmed before installation.
