Abstract

A vehicle lamp assembly comprises a light source (16), a light transmitting outer element (24) and a cylindrical light transmitting intermediate element (18) disposed between the light source (16) and the outer element (24) with the light source (16) on its cylinder axis. The intermediate element (18) has elongate Fresnel prism formations (22) of uniform cross section on its outer surface which extend in respective planes perpendicular to the cylinder axis so as to collimate light from the light source (16) into said planes. A second set of elongate Fresnel prism formations (26, 28), formed on the outer element (24), is oriented parallel to the cylinder axis of the intermediate element (18).
