Auto Courtesy Light Devised (May, 1938)
Auto Courtesy Light Devised
BETTER road manners may result if an automobile signal device recently placed on the market becomes popular. Mounted on the radiator cap or at the rear of the auto, the device enables the driver to acknowledge courteous driving on the part of another motorist by flashing the words “Thank You” in illuminated letters, which are visible night or day. A control on the dash or steering wheel operates the signal light and drivers report that passing motorists are first surprised, then pleased, by the unusual display of highway courtesy.
