ABSTRACT:
According to the invention clear and yellow transparent zones are provided on the surface of a light diffusing element associated with a headlamp for a moving vehicle. The light emitted from the lamp has the characteristics of both white and yellow light. High intensity white light provides satisfactory illumination for highway driving, while the yellow light emitted penetrates fog, dust and/or smoke better than the ordinary white light. The benefits of both light are realized with a single lamp. The coloration of the light diffusing member can be accomplished by treating a conventional white light headlamp.
