ABSTRACT:
System and method for monitoring status of a visual signal lamp. The system includes at least one optical fiber comprising a first end and a second end. The first end is positioned proximate to the signal lamp and is oriented to capture a portion of light signal emitted by the signal lamp when the signal lamp is illuminated. The system also includes a photodetector positioned proximate to the second end of the optical fiber and configured to receive the portion of light signal. The system further includes a threshold detection circuitry connected to the photodetector and configured to detect a lighting parameter in relation to the signal lamp according to a predetermined criterion.
