Abstract
A load status indicator is disclosed for determining whether power is available to, and current is flowing through, a load. A first visual status indicator may light up when power is available to the load but current is not flowing through the load. A second visual status indicator may light up when power is available to the load and current is flowing through the load. A bi-color light-emitting diode may comprise the first and second visual status indicators. Transistors may be used to permit or prevent current from flowing through the visual status indicators. In some embodiments, a reed switch or a hall-effect sensor may be used to determine whether current is flowing through the load.
