She never headed any automobile company. However, her name is indispensable in this list. Invented modern day "turn signal", and "brake lights".

She was a well known Canadian-American actress during 1910s. Although she wasn’t the first person to develop a turn signal, she was one of the pioneers of the idea. Her turn signal was a mechanical arm that lifted a flag on the rear of the car. She also developed a mechanical brake signal that unfolded a “stop” sign from the back bumper when the brake was pressed.
