Thinking of the new upcoming class of separate position lamp with frosted, matted, opaque, structured, or otherwise non-transparent outer lens materials lighting specialists face a new challenge in position lamp design. It is no longer enough to fulfill all required ECE or SAE regulations, the outer lens becomes a new styling element with advanced corporate identity requirements. Uniformity - even in systems with more than one bulb - takes the first place in designer's wish list. The concepts presented in the paper point out the requirements for a separate position lamp using supplementary optical elements in dispersion or reflection technique in combination with a matted or none transparent outer lens. New technologies afford new solutions for the design of ordinary positions lamps. One great challenge concerning these materials is to create a uniform signal image in the outer lens region. Based on a reflector design which produces a possibly smooth basic light distribution additional optical elements help generating a more uniform light distribution by redirecting the direct light from the bulb. One promising approach is the use of transparent optical elements based on the principle of total internal reflection which are keeping the brilliance in day as well as night design and reducing the direct light from the bulb about 50%. Furthermore this optics can be used to form a specific virtual image of the bulb filament.
