ABSTRACT:
Delayed perception of the brake signal, a significant contributing factor in many rear-end automotive vehicle collisions, is a problem not totally resolved by the addition of a red colored supplementary brake signal light. A more effective and esthetically superior approach is employed in the current invention, in which red colored light, and only red colored light, is displayed at the rear of a vehicle during braking; and further, in which non-red colored light, and only non-red colored light, can be displayed at the rear of said vehicle when the brake actuation means is not actuated. If illuminated, non-red tail lights and rear turn signal lights are extinguished during braking, replaced by red colored brake signal lights, one of which may flash to indicate an intended turn, said red colored lights being extinguished and said non-red colored lights being re-illuminated upon release of the brake actuation means. Thus, the display of red colored light per se provides an unambiguous, immediately perceptible signal of braking.
