Léonide Belovsoroff’s automobile direction indicator, photographed in December 1928. Developed before the use of blinking lights became widespread to indicate a change in direction, this indicator was intended to take the place of arm signals, which were the main turning indicator used at the time, as they still are for cyclists. The indicator was in the shape of a hand that was raised and lowered by a coil activated by an electrical system installed at the steering wheel.
