Abstract: A warning light assembly includes a source of electrical power, an LED light source, electrical circuitry operably coupling the source of electrical power to the light source and a lens assembly. The lens assembly encloses the LED light source such that light from the source is directed outwardly from the lens assembly. The lens assembly is triangular in shape. In certain embodiments, the electrical power source includes a rechargeable battery and the assembly further comprises a solar panel operably connected to the rechargeable battery. A triangular lens assembly may be connected at a vertex to a housing which holds the electrical power source. The solar panel may be mounted on a peripheral surface of the lens assembly opposite the vertex.
