What is the function of an indicator light within a circuit?

Explanation:
Indicator lights provide a visible status of a circuit or subsystem. They light up when a part of the circuit is energized or in a particular state, giving a quick at-a-glance indication that the circuit is ON, a device is ready, or a condition has been met. This helps technicians monitor operation and diagnose problems without tracing wires. They are not used to cool components, act as fuses, or supply power—they simply signal the circuit's status by emitting light in response to electrical current.
