Abstract
A signaling lamp monitor is configured to add a communication function to a signaling lamp such as a stack signaling lamp easily and at a low cost. The signaling lamp monitor includes a detector that detects light emitted from the signaling lamp, a controller that generates a detection signal at least based on the detection, and a transmitter that transmits the detection signal by wireless communication. The transmitter is provided with an antenna disposed above the detector.
