A SUBJECTIVE EVALUATION OF TURN SIGNAL EFFECTIVENESS

This paper is a subjective assessment of the effectiveness of flashing signals which go from signal intensity to off rather than from signal intensity to presence intensity. The results indicate that the former configuration would be undesirable first, because there appears to be little benefit in increased signal effectiveness by such an arrangement; second, in the event that the signal filament is burned out, one side of the car would be unmarked when the turn signals are used.
