Abstract: A luminosity intensity monitoring system for maintaining compliance with a regulated level of visibility of specific-purpose lighting systems. The luminosity intensity monitoring system may be compatible with both incandescent and LED-based lighting systems, and may incorporate “smart” technology built into a luminaire or separately installed circuitry, and may be installed as original equipment or configured for retro-fit applications. The luminosity intensity monitoring system may be configured to present an early visible or audible warning which may indicate the visibility of a luminaire may be at risk of being non-compliant with regulations set forth by convention or civil authority.
