A method and apparatus are provided for remotely monitoring the status of a variety of illumination devices. A fiber optic cable coupled to a light fixture transmits a light display. Based on the light received, the status of the light is determined. The status is determined without the use of elegant and expensive electronics that are more subject to failure and with minimal power consumption.
