Abstract

A compact and highly efficient warning light for producing high intensity light pulses which are radiated in accordance with a desired directional pattern includes a light source and at least a first reflector disposed within a lens cover. The reflector is coaxial with the lens cover, includes plural parabolic reflective surfaces arranged in a symmetrical pattern and having a common focal point located on the axis of the lens cover, and reflects light in directions which are generally transverse to the lens cover axis. The lens cover is provided with internal optics which redirects light emitted by the source which is not reflected, such redirected light also being radiated in directions generally transverse to the lens cover axis.
