A visual indicator associated with a documented control or equipment condition.

## What it represents

An indicator lamp shows an operating condition defined by its circuit and label. The generic representation identifies an indicating element; it does not define what illumination means, the supply voltage or whether the device is continuously lit or flashing.
A schematic should explain the condition driving the indication. The front-panel description should match the electrical label, so a reviewer can follow the indication from operator interface to contact, relay or controller output.

## How to read it

- Read the text describing the indicated condition.
- Follow the circuit supplying the lamp and identify any flashing or test function.

## Information to show or reference

- Record the indication label.
- Reference the supply and device type.
- Align schematic identification with the panel layout.

## Important distinction

An indication mark does not establish that equipment is safe, isolated or de-energised. Its meaning comes from the full circuit and operating documentation.
