Abstract
Abstract A vehicle lamp assembly has a light source, a light transmitting member, baffle elements of light absorbing material extending perpendicular to the surface of the light transmitting member towards the light source and lens means located between the baffle elements and the light source so as to concentrate light from the light source between adjacent baffle elements. The ends of the baffle elements abutting the light transmitting member are of a color chosen in accordance with the required appearance of the lamp assembly when the light source is not illuminated and the rest of the baffle elements are black.
