Stoplight Flashes Automobile Turn Signal on Pavement (Apr, 1934)
Stoplight Flashes Automobile Turn Signal on Pavement
AT LAST an automobile stoplight has been invented that will project its signals on the street behind in letters large enough to be easily read.
The French invention fulfills in all respects the “Needed Invention” in this field described in the September, 1933, issue of Modern Mechanix. A powerful electric bulb, a lens system, and lantern slides are combined to project lettering onto the street behind. Operation of the indicator may be controlled by the driver, or automatically by direct connection with steering wheel and brake pedal.
