The CR2530 Series remote electrical current indicators offer the unique advantage of an economical method for providing a visual indication of current flow. Reportedly, they are easy to install and factory calibrated to provide a preset turn-on point. A bi-polar LED illuminates when the current reaches above the turn-on point. The LEDs are self powered and available in six color options: red, green, blue, white, yellow, or amber.
