Lighting system and method of use thereof

A dynamic lighting system for use along a length of an underground passageway, the system comprising:

• a base station comprising at least one power source;
• a plurality of light modules extending from the base station in a serial arrangement and spaced at least partially along the length, each light module configured to emit light for ordinary operations within the passageway and at least one visual signal;
• at least one cable extending from the base station and interconnecting the light modules with the base station and the power source;
• a controller operatively associated with the base station, said controller being in communication with at least one sensor configured to sense an environmental condition, said controller configured to continuously monitor said sensor and selectively activate the at least one visual signal of any one of the light modules when an abnormal or emergency said environmental condition is detected;
• and
• each said light module further comprising a redundant wireless communications module, a redundant power source and a dedicated microprocessor operatively associated with the at least one visual signal enabling operation of the at least one visual signal in response to receiving wireless instructions from the controller should the at least one cable connecting the light module to the base station be damaged or severed,
• wherein the light emitted for ordinary operations is white light and the at least one visual signal is selectable from a flashing non-white light and a constant non-white light, and
• wherein, when said at least one visual signal is a flashing non-white light, the light modules are configured to flash the at least one visual signal relative to one another in a sequential and coordinated pattern to direct a person away from the abnormal or emergency said environmental condition.
