The first vehicle indicator system was created by a woman, who’s name was Florence Lawrence.

In 1914,  the silent-film movie star, named Florence Lawrence, invented the first “auto signalling arm,” a mechanical turn signal, along with the first mechanical brake signal.

Being a successful actress, Lawrence was able to buy her own car. She adored driving and loved learning about the way automobiles worked. “A car to me is something that is almost human,” she said, “something that responds to kindness and understanding and care, just as people do,”  Lawrence told a reporter in 1920, when driving had become a symbol of women’s liberation. “The average woman does her own repairing. She is curious enough to investigate every little squeak of her car, and to remedy it.”
