ABSTRACT:
The present invention provides a navigational safety lighting system for use in low visibility conditions caused by fog, mist, rain, snow or other particulate matter in the atmosphere. A laser light source is utilized which emits a beam of laser light that is visible to the naked eye when it strikes the particulate matter in the atmosphere. The laser light source may be mounted on an air, water or land craft, or may be mounted on navigational or other objects to identify them in such low visibility conditions. Also, the laser light source on an air, water or land craft may be directed in the direction of movement of the craft to identify obstacles in the path of the craft in such low visibility conditions.
