1. A vehicular auxiliary lamp comprising:
a housing;
a lighting assembly disposed within the housing, the lighting assembly including:
a printed circuit board (PCB),
an optical manifold mounted on the PCB, the optical manifold comprising:
a plurality of road illuminating reflective cavities arranged adjacent one another along a length of the PCB, each one of the plurality of reflective cavities: defining a respective corresponding focal point, intersecting at least one other one of the plurality of reflective cavities at an intersection region, and having a bottom surface facing the PCB and a top surface opposite the bottom surface, and
a plurality of signaling reflectors, each of the plurality of light signaling reflectors being disposed over a top surface of the road illuminating reflective cavities at a respective one of the intersection regions,
a plurality of road illuminating light sources on the PCB with a center of each road illuminating light source aligned with the focal point of a respective corresponding road illuminating reflective cavity, and
a plurality of light signaling light sources with a center of each of the plurality of signaling light sources aligned with a focal point of a corresponding signaling reflector.
