These blue dot tail light lenses were very popular in car enthusiasts back in the 50’s. They would show a purple cast especially from the stop light when the brakes were applied. Many state out lawed them because of their color. This is from a 1940 Chevrolet at a Car show in Sequim, Washington. The robin egg blue color on this Chevy was also very popular back then ~ Lynn
