Abstract: A window system for manufacturing fixed windows using only two main extrusions, a main frame, and sash frame; and for manufacturing vertical and horizontal sliding windows using only three main extrusions, a main frame, a sash frame, and an interlock. This overcomes the disadvantages of existing window assemblies that currently need multiple extrusions, and results in reduced retooling costs, permitting manufacture of window systems using newer, more energy efficient materials including silicon-based materials.

Abstract: A reflectorized lighting device is disclosed having a flange that at least partially surrounds the periphery of the reflectorized lighting device. The reflectorized lighting device can have an aperture adapted to receive a light source. The flange can be adapted to receive a reflector. The reflector can be received by the flange and can at least partially surround the periphery of the aperture. The reflector can be integrally formed with the flange, light source, or housing. The flange can be integrally formed with the housing, light source, or reflector. The light source can be integrally formed with the housing, flange, or reflector. The reflectorized lighting device can be used to retrofit existing vehicles or can be used on newly manufactured vehicles.
