The present invention relates to a beacon light (100) for aviation obstacle warning comprising an elongated body portion formed into a hollow tube (19), a plurality of light emitting diodes (LEDs) (10) mounted on the outer surface of the hollow tube (19) and electrically connected together to form a substantially cylindrical array of LEDs (10), characterized in that a plurality of grooves (21) are formed axially on the outer surface of the hollow tube for arranging the array of LEDs (10) in a substantially cylindrical and orderly manner, and the hollow tube and the LEDs (10) being encapsulated with sealing composition (11), wherein at least a part of the lens body of the LEDs (10) protrudes out from the surface of the encapsulation to allow the direct emission of light. The LEDs (10) are affixed along an elongate conductor set within the grooves (21) and the surface of the body portion. The beacon light (100) which is very compact, light weight for use high up on communications towers and in an around airports, etc. The clear portion of the LED lens to project the light directly outwards 360 degrees horizontally and with a vertical beam width of 15-35 degrees. This eliminates the need for a dome or covers over the LEDs that cut down effective light output. This construction further improves heat conduction and cooling from direct convection of air. It is particularly good for keeping out moisture from causing deterioration of the electrical and electronic circuits in the light (100) in hot and humid tropical climates and for long term operation of the light (100).
