First U.S. turn signals


“Buick was the first U.S. automaker to offer factory-installed flashing turn signals. Introduced in 1939 as a safety feature, the new-fangled feature was advertised as the ‘Flash-Way Directional Signal’ operated from a switch on the new ‘Handi-shift’ column-mounted shifter. The flashing signals only operated on the rear lights.


“In 1940 Buick enhanced the directional indicators by extending the signals to front lights and adding a self-canceling mechanism.”

  1. P.S. I knew this blog would be good when you mentioned Streamline Moderne and your focus on California — both of which are passions of mine 🙂
