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 a pair of reflectors disposed within a lens cover. The reflectors each include plural parabolic reflective surfaces distributed about an axis with the surfaces having a common focal point located on the axis. The two reflectors are coaxial and the common focal points of the surfaces thereof coincide.
