Abstract
A warning light has multiple juxtapositioned arrays of light emitting diodes, each of the arrays defining a plane oriented transversely to the parallel axes of the lenses of the diodes comprising the array. The arrays are supported so that the planes defined thereby angularly intersect. The radiation pattern of the light is controlled by selection of the diodes comprising each array and adjustment of the angles of intersection of the array defined planes.
