What many of our American readers probably do not know is that until 1993 all cars in France were required to have yellow headlights. This tradition started during World War II so that the French civilian cars would stand out form enemy vehicles. The Government enacted a law on the 3rd of November, 1936 stating that all vehicles put into production in 1937 are required to have yellow headlights. The French being who they are, didn't abandon these headlights until 1993 when forced by the European Unions conformity standards. Today, it is illegal to drive in France with yellow headlights unless your car was first registered before 1993.
