Panel indicators, pilot lights, and other illuminated display components can be found in many applications, from home electronics to industrial control systems. Whether they are used to indicate a change in status, the presence of power, or alarm conditions, panel indicators and pilot lights can be a helpful warning system which can alert personnel of potential hazards or changes in conditions.

The panel indicators and pilot lights typically used with these systems can be either discrete devices or integrated into larger systems. Discrete devices are powered directly from the main power supply and can be used with a variety of control and monitoring systems. Integrated systems are connected directly to a display panel and provide a range of important information such as status, alarm, and other notifications.

Panel indicators usually work by providing a visual indication of a change in status or presence of power. In the simplest cases, a flashlight, light emitting diode (LED), or incandescent lamp will be used as the visible part of the indicator. Depending upon the specific application, the LED or lamp will be either illuminated or extinguished when activated. These devices are usually either connected directly to the power supply or soldered to the power supply via a circuit board, allowing the device to be powered even when the power supply is off.

Pilot lights work in a similar manner, but instead of providing a direct indication of a change in status, they provide an audible warning when activated. Typical examples include ringing bells, buzzers, or sirens. These types of devices can be found on the front of control panels, fire alarms, or other devices. Pilot lights are connected to the other components of the system via wires to ensure the alarm is triggered whenever the alarm is activated.

In addition to indicator lights, many systems also employ a variety of sensors to detect changes in environmental conditions. These include temperature, pressure, smoke, and water. These sensors are connected to the main system via wires or infrared technology, and allow the system to detect changes in the conditions which would require it to sound an alarm.

Another type of system which uses both indicator lights and sensors is a data logging system. Such systems are used to collect data from the environment, such as temperature or pressure, for analysis. The data can be used to trigger alarms when conditions exceed predetermined limits, or can be used to log the data for later analysis.

Panel indicators, pilot lights, and sensors are all a valuable asset to applications in both the home and the workplace. By providing a warning system which can alert personnel of potential hazards or changes in conditions, these systems help to ensure safety and productivity.
