1. A method comprising:

  • obtaining, at an electrical circuit and in accordance with a current requirement of an electrical equipment, current from a power source;

    comparing, using the electrical circuit, the obtained current with at least one of a first threshold and a second threshold;

    if the obtained current is less than a first threshold, activating one or more light emitting diodes of a first color;

    if the obtained current is equal to or more than the first threshold and is less than a second threshold, activating one or more light emitting diodes of a second color; and

    if the obtained current is equal to or more than the second threshold, activating one or more light emitting diodes of a third color, wherein the electrical circuit includes a latching mechanism that enables the color of the activated one or more light emitting diodes to be retained after the electrical equipment stops being used.
