Q: What happens if one LED fails?
A: Redundant circuitry provides a second independently operated LED of opposite polarity for each phase, thereby leaving one LED to indicate voltage on that given phase. For DC systems, connecting (2) leads to the DC+, (1) to DC Common, and (1) to Earth Ground provides redundancy.
