Indicator Light
What Is an Indicator Light?
An indicator light, also called a LED indicator light, pilot light, or panel indicator light, is a visual signaling device used in electrical equipment, industrial machinery, automation systems, vehicles, and electronic devices.
Indicator lights provide instant visual feedback about machine or system status, including:
- Power ON/OFF
- Machine running status
- Warning or fault alarms
- Standby mode
- Emergency stop conditions
- Low voltage or overheating alerts
Modern LED indicator lights offer high brightness, low power consumption, vibration resistance, and long service life exceeding 50,000 hours.
They are widely used in:
- Industrial control panels
- CNC machines
- Automation equipment
- Automotive dashboards
- Marine systems
- Medical equipment
- Power distribution cabinets
- Home appliances
