Abstract
Confusion of red colored automotive brake signal lights with other red lights delays perception of the brake signal. Perceptibility of the brake signal is improved when red colored lights are displayed only during braking, non-red colored lights being displayed at appropriate other times. The current invention effects this color distinction by interposing, during braking, low electric resistance into electric circuits between a source of electrical energy and lamps effecting red colored light, and interposing high electric resistance into electric circuits between said source of electrical energy and lamps effecting non-red colored light, and further, by interchanging the said interposed electric resistances when the brake actuation means is not actuated, flow of energizing electric current being sufficient to effect illumination of said lamps only in the case that said interposed electric resistance is low.
