Abstract: A signal system for an automotive vehicle, especially a system for giving an early signal to a following vehicle and particularly characterized in that an amber light visible from rearwardly of the vehicle is illuminated when the engine is running and the vehicle is not accelerating or braking. When the vehicle is accelerating by depressing the accelerator pedal the amber light changes to green and when the vehicle is braked as by applying the brake pedal, the signal light changes to red. When braking while the turn signal is operated, one red lamp is illuminated continuously while another is illuminated intermittently and alternately with the amber lamps. When the four-way flashers are turned on all the turn signal lamps alternate with the amber lamps. In this manner, clear and distinct signals are provided, especially for a vehicle following the vehicle having the signal system thereon.
