Shop Indicator Lights & LED Light Panels on Amazon.com
LED light panels and other indicator lights give a visual indication of system status at a glance. An indicator light may use one of several light sources. Incandescent panel indicator lights are a common type. Increasingly, LED indicator lights are being used in panel mount indicator lights. An LED light panel draws less current than other forms of bulb. An indicator light is used individually in applications such as automotive dash panels. Multiple indicator lights are used in system control panels and in test panels. A LED indicator light may be purchased individually or in packages of multiple bulbs. LEDs are available for use in a variety of voltages and in both AC and DC. LED light panels may display pilot lights that indicate system operation, or they may display flashing warning lights that indicate a system error. In some applications, a sound indicator, such as a buzzer, is used in addition to a light indicator. One advantage in using a light indicator panel over a sound indicator is that the circuit with the error can be more quickly identified.
