FIELD: transport.
SUBSTANCE: invention relates to sea navigation devices. Proposed navigation light comprises cylindrical lens, light source, power supply connected to light source. Proposed light additionally comprises programmator. Set of n-LEDs makes light source arranged on the lens inner surface along R-radius circle and at height equal to H/2 from lens base where H is lens height. Each LED has its light diagram directed toward lens center. Lens accommodates R/2-radius cylinder with its axis aligned with lens axis. Cylinder side surface makes a mirror, while power supply control input is connected to programmator output.
EFFECT: longer life, higher reliability, programmed light and pause duration at equipment location.
