Abstract: A safety system for early lighting of stop lights in vehicles comprises the step of measuring the negative rate of change in the fuel supply to the engine, and converting same to an electronic analog or digital value; the step of comparing the value corresponding to the negative rate of change in the fuel supply to the engine to a preassigned threshold level; and the step of lighting the stop lights if the value is larger than the threshold value.
