Abstract:
A light assembly includes a light source circuit board and a plurality of light-emitting diodes disposed on the light source circuit board. A plurality of light pipes axially extends from and adjacent to each light-emitting diode. Each light pipe has a respective first end adjacent to the plurality of light-emitting diodes and a second end opposite to the light-emitting diodes. The plurality of light pipes communicates light from the light-emitting diodes therethrough and defines a cavity therebetween. A plurality of thermal vanes forms a heat sink for removing heat from the light-emitting diodes. The plurality of thermal vanes extend adjacent to the plurality of light pipes. A driver circuit board is disposed within the cavity.

Abstract:
A light assembly includes a light source circuit board, a plurality of light sources disposed on the light source circuit board, a housing thermally coupled to the light source circuit board and a lens cap assembly comprising a lens cap and a heat dissipation layer. The heat dissipated layer distributes heat from the light source circuit board through the lens cap and external to the light assembly.

Abstract:
An electrical switching unit includes a first switch for positioning a vehicle component or activating a memory function. A second switch controls the first switch to select between positioning the component or activating the memory function. Preferably, the switching unit controls the positioning of the right and left side mirrors and activation of a memory function. In one embodiment, the second switch has three positions to select right side mirror positioning, left side mirror positioning, or memory function. The first switch includes four sub-switches to control the upward, downward, inward, and outward adjustment of the right and left side mirror and activation of the set and recall modes of the memory function.

A light assembly includes a heat pipe having a first condenser portion and a first evaporator portion. The heat pipe includes a longitudinally extending wall. A plurality of light sources are disposed at least partially around and thermally coupled to longitudinally extending wall at the first evaporator portion of the heat pipe. A first heat sink housing receives the first condenser portion of the heat pipe.
