Annunciator Panel

A panel of warning lights in plain view of the pilot of an airplane or the operator of other types of equipment. The lights are identified by the name of the system they represent and are usually covered with a colored lens to show the meaning of the condition they announce. Red lights are used to indicate a dangerous condition, amber lights show that some system is armed, or active. By having all the lights together in an annunciator panel, the pilot or operator can determine the overall operating condition of the equipment at a glance.
