LEDs, or light emitting diodes, are small, durable and energy-efficient indicators used for indicating the status of a product or process. LEDs are rated for long-term operation and can provide a robust, reliable indication of process information. There are two types of LEDs, discrete and non-discrete, which are used for different applications.

Discrete LED indication is used in applications where limited information needs to be conveyed. A discrete LED communicates a binary indication; either on (illuminated) or off (not illuminated). This binary indication can be used to communicate a variety of simple states. For example, a discrete LED could indicate "power" in an application, implying that if the LED is on, power is present, and if the LED is off, no power is present.

The working principle of a discrete LED is straightforward. When a voltage is applied to the LED, in the direction indicated on the package, current flows through the device, exciting the electrons and producing light. The light from the LED is proportional to the current through the device, up to a certain limit, beyond which the device will be damaged. The intensity of the light emitted is controlled by either adjusting the current, controlling the pulse width, or varying the voltage supplied to the device.

One of the most common applications of discrete LED indicators is in the avionics field. Avionics are used in aircraft to provide a way for pilots to manually control the aircraft. In order to provide an intuitive way for pilots to interact with the aircraft, LED indicators are used to signal activation and deactivation of various components and systems. For example, discrete LED indicators are used to signal power on and power off, gear up and gear down, condition lever up and down, overspeed and underspeed conditions, and autopilot activation. LEDs can also be used to indicate that a certain system or component is enabled, such as a navigation system, a landing gear, or a thrust limit system.

Discrete LED indicators can also be used in industrial and consumer applications. In industrial applications, discrete LED indicators are typically used to signal simple binary states, such as "on" and "off". For example, an LED indicator could be used to indicate a power-on state for a machine, or a process-monitor state for a laboratory instrument. In consumer applications, discrete LED indicators can be used to indicate the status of a system or device, such as a microwave oven, kitchen timer, telephone message system, or printer status.

LED indicators have become increasingly popular in a variety of applications due to their low cost, robustness, and energy efficiency. Discrete LED indications are a simple and intuitive way to convey limited information in a variety of applications. They are used to easily convey a simple binary state, alert busy pilots to changing conditions, and even remind us when our sweet potato pie is finished baking.
