Abstract
A light-emitting assembly configured to generate varied color light includes an assembly housing. The light-emitting assembly also includes a light filter element fixed relative to the assembly housing. The light filter element includes a plurality of transparent nanostructured ElectroChromic (TNEC) layers. When at least one of the plurality of TNEC layers is subjected to voltage, the subject TNEC layer(s) imparts a distinct reflective color to ambient light entering the light-emitting assembly. Such a light-emitting assembly may be specifically adapted for use on a motor vehicle.
