A dual beacon is provided for mounting on an obstruction such as a tower. The dual beacon is substantially cylindrical with an open cylindrical interior. An upper lens section and a lower lens section is provided and at the inside top of the upper lens section there is a slight, outward and downward taper of about 1.degree.. The upper lens section and the lower lens section are hinged to allow access to the interior where a plate has an upper flashtube assembly and a lower flashtube assembly mounted thereon. The member is hinged to allow easy access to the upper flashtube assembly and to the lower flashtube assembly. The upper lens section and the lower lens section each have a central portion which controls the intensity of the light beam. The peak intensity is in an area of 3.degree. through 5.degree. above a horizontal reference plane and in an area of 1.degree. below such horizontal reference plane greater than 50% of peak intensity is provided. Each flashtube assembly includes a socket having openings which allow positioning of an elongated member over which a flashtube is positioned. Each socket is drilled with openings to accommodate wiring for the flashtubes and to provide simple yet effective mounting on the hinged member inside the dual beacon.
