A lighting assembly includes an on/off source of light and an optical diffuser characterized in that it receives light from the source and emits it in a desired viewing direction, but with underlying surfaces being at least diffusely visible therethrough. Thus, in an automotive or other vehicular application, the surface may be a body panel, the color of which may be visibly evident through the diffuser panel, thereby enhancing desired aerodynamic/styling characteristics. The source of light preferably comprises one or more semiconductor devices such as light-emitting diodes, and the optical diffuser is holographically recorded and provide high transmission and low backscatter to shape the emitted light in addition to its redirection in accordance with a desired beam profile or cross section.

[ Having thus described my invention, I claim:] [1.] A light-emitting assembly for installation over a colored surface, comprising:a source of light which may be turned on and off;a visibly featureless optical diffuser having a back surface to receive light directly from the source and a front surface from which the light emerges in a predetermined scattering pattern, the diffuser having sufficiently high light transmission and low backscatter that the colored surface is at least diffusely visible through the diffuser when the source of light is turned off.
