Voltage Indicator LEDs

Voltage indicator LEDs are 3 phase, switchboard mounted, power indicator lights.  They are used to verify that an electrical isolation switch, circuit breaker or disconnect is open, as part of a lockout procedure.  So they are normally used to determine a lack of voltage presence.  In other words, voltage absence.  Voltage indicator LEDs are also known as:

• 3 Phase indicator lights / 3 Phase indicator LEDs / 3 Phase indicator lamps 
• Live line indicator lights / Live line indicator LEDs / Live line indicator lamps
• Mains indicators lights / Mains indicator LEDs / Mains indicators lamps 
• Power indicators lights / Power indicator LEDs / Power indicator lamps 

The DeadEasy voltage indicator is permanently installed in an electrical panel and incorporates a self test facility.  It provides positive indication (Green LED) when the switch is off (voltage absence) and positive indication (Red LED) when the switch is on (voltage presence).
