A vehicular lighting assembly (and methods of making the same) that includes a parabolic reflector; a condenser lens comprising a non-planar rear surface; an outer lens; a bezel between the lenses; and a light source that emanates light that strikes the reflector and exits the assembly through the condenser lens and the outer lens. Further, the non-planar rear surface of the condenser lens refracts ambient light entering the condenser lens away from the bezel. In embodiments, the non-planar rear surface can comprise a convex or a concave surface.

LED light bulbs include openings in base or cover portions, and optional forced flow elements, for convective cooling. Thermally conductive optically transmissive material may be used for cooling, optionally including fins. A LED light engine may be fabricated from a substrate via planar fabrication techniques and shaped to form a substantially rigid upright support structure. Mechanical, electrical, and thermal connections may be made between a LED light engine and a LED light bulb.

A light assembly includes a laser light emitting diode for emitting a light beam along an axis and a diffusing assembly for deflecting the light beam substantially 360 degrees around the axis. The diffusing assembly includes a light diffuser for receiving and scattering a light beam emitted from the diode, a phosphor tube for further scattering the light emitted from the diffuser, and a mirror for returning any light with is not deflected radially through the phosphor tube back into the phosphor tube. The deflector has a reflective end surface to allow the light repeated passes thorough the phosphor tube until it escapes radially through the tube.
