Contrary to popular belief, the American federal government did not mandate amber lights, seat belts, gear quadrants or anything else prior to 1966 as they did not have the power to do so. It was not until 1966 that the American federal government gained such powers with the enactment of the National Traffic and Motor Vehicle Safety Act. It was at that point the federal Department of Transportation was established. Prior to that the states had power over vehicle regulations. In 1957 some car makers, such as Imperial, introduced the four headlamp system, but could not sell it in all states as some had not yet approved it. Same with sealed beam headlamps on the 1940 models. Manufacturers had to wait until all 48 states (and all 9 provinces in Canada) approved them before they could be used. And their approval did not outlaw the old bulb and reflector system in all areas, which permitted Graham and Hupmobile, for example, continue to build cars without sealed beam headlamps. In the case of the amber bulbs / lenses for the 1963 model year, that was the result of a recommendation of the board of directors of the Automobile Manufacturers Association. The AMA had conducted tests and concluded that amber signals could be seen more easily against glaring reflections that white signals. Pior to the establishment of the Department of Transportation, the AMA played a large role in establishing safety and equipment guidelines for the American auto industry, including sealed beam headlamps, the quad headlamp system, safety belts and front amber turn signals. By the way, although Valiant, Dart, Dodge 880 and Imperial all had amber lenses in 1963, while Plymouth only came in clear, Dodge (B body) and Chrysler had both listed for that year.
