Stoplight is a complete, inexpensive high resistance grounding system that provides system wide protection against damaging ground faults. Using a simple but effective three light system, Stoplight provides visual indication and available remote annunciation to inform operations and maintenance personnel of ground faults.

A red light indicates an active ground fault, an amber light indicates a ground fault has occurred but is intermittent and a green light signifies that there are no active ground faults on the system.
