Panel indicators, also referred to as indicator lights or pilot lights, are electronic components that provide visual indication of the status of electrical equipment. They work by emitting a visible light when electrical current passes through them, signaling the presence of power. These indicators are common in a variety of industrial and electronic applications.

Panel indicators are typically used in process control applications, and are available in a wide variety of shapes, sizes, and colors. They allow electronic equipment operators to instantly determine the status of the system or device, without the need for a manual inspection or measurement. The colors of the indicators can be used to signify a specific status such as "on", "off", "safe", or "dangerous". The colors can also change according to changes in the system, for example when a system is "alert".

Panel indicators are typically powered by DC or AC current, provided by a wide variety of voltage sources. The current passes through the indicator, activating the light-emitting diode (LED). The LED is usually colored in red, green, yellow, and blue in order to identify the relevant status. In some cases, LEDs of multiple colors are used, provided that the appropriate power is supplied.

Panel indicators are otherwise known as "pilot lights", because of their classic design and installation as part of a legacy panel. They are typically installed in series with the circuits they monitor, and can be used for both AC and DC installations. In both cases, the power input to the indicator must be in the appropriate range for the LED to be activated.

Panel indicators have several advantages over traditional signal indicators, including: high durability, low power usage, and high visibility. The indicators are designed to be long-lasting and they are typically resistant to a wide range of environmental conditions, such as extreme temperature and pressure. The LED also requires significantly lower power than its predecessors, thus reducing energy consumption. Finally, the LED is highly visible, making it easy to detect the status of a system or device without the need for manual inspection.

In conclusion, panel indicators, or pilot lights, are essential electronic components used to provide visual indication of the status of electrical equipment. They are commonly used in a wide range of industrial and electronic applications, and they offer several advantages such as high durability, low power usage, and high visibility.
