Panel Indicators, Pilot LightsPanel indicators and pilot lights are small visual signaling devices that are used to indicate the status of a device or system. Panel indicators are typically small, colored lights that are used to indicate the presence of power, the state of a system, or other information. They are often used in control panels, displays, and other applications where visual signaling is needed. Pilot lights are similar to panel indicators, but are often larger and use a more intense light source. They are commonly used in industrial and commercial applications where a more visible signaling device is needed. Both panel indicators and pilot lights are available in a variety of colors, sizes, and styles, and can be panel-mounted or surface-mounted, depending on the specific application.
