Abstract
A laser lighting system which employs employ visible and reflective laser beam lighting sources to provide illumination of airport runways and taxiways, preferred approach and departure routes, seaplane base landing areas, marine waterways, as well as to assist in search and rescue operations. The lighting system includes handheld laser lighting units or flares particularly useful for search and which have an optic which emits a laser beam for generating a laser line which is uniformly illuminated from end to end. The handheld laser lighting units may have a pistol grip housing or a cylindrical housing, and may feature either a trigger switch, a plunger switch, or a rotary switch. The handheld laser lighting units are battery powered, and include waterproofing seals for protection from the elements.
