An innovative solution to continuing misuse of red light on automobiles

A novel approach [referred to as the RLMS (Red Light Means Stop) approach] to automotive rear lighting has recently been suggested as a means to enhance perceptibility of the rear lights. In the RLMS approach, only red colored light is displayed during braking, and only amber colored light is displayed at other times. Color per se then provides, for most drivers, an immediately perceptible visual stimulus by which brake lights are distinguished from tail lights. In earlier testing, simultaneous display of nonred tail lights and red brake lights confronted test subjects with antagonistic visual stimuli, thereby compromising, and underutilizing, the value of color. It is suggested that the potential safety value of the RLMS approach is significant, and that comprehensive testing should be conducted in a timely manner.
