Abstract

A lighting system and method of use is disclosed for use with an underground passageway. The lighting system includes a base station having at least one power source, and a plurality of light modules extending from the base station in a serial arrangement and spaced at least partially along a length of a passageway. Each light module is capable of emitting light for ordinary operations within the passageway and at least one visual signal. The system further includes at least one cable extending from the base station and interconnecting the light modules with the base station and the power source and a controller operatively associated with the base station and in communication with at least one sensor configured to sense an environmental condition. The controller is configured to continuously monitor said sensor and activate the at least one visual signal when an abnormal or emergency environmental condition is detected.
