Abstract
One embodiment of a vehicle lamp assembly may include a housing, which includes a pair of opposing reflective surfaces defining a chamber therebetween. The assembly may further have a single light emitting diode (LED) disposed within the chamber and a lens carried by the housing. At least one of the reflective surfaces may have a grain pattern configured to interact the light emitted from the single LED with the housing in a range between one and five times before the housing directs the light through the lens.
