An LED indicator assembly provides a documented visual signal using a semiconductor light source.

## What it represents

An LED indicator assembly provides a documented visual signal using a semiconductor light source. Its rated supply, polarity where applicable and indication meaning must be specified.

## How to read it

- Differentiate the complete indicator assembly from a bare LED component.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- State assembly voltage
- Name indicated condition
- Reference polarity/terminals

## Important distinction

A rated panel LED indicator may contain internal circuitry beyond a bare light-emitting diode.

## Facts

- Drawing role: Visual signal
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HLT1H25, VLT1H25 (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
