Car lights are various traffic lights installed on cars to ensure safe driving. There are two types of lights and signal lights. From 1905 to 1912, in order to solve the problem of lighting the road ahead, spotlight-type acetylene headlamps were installed, and a kerosene lamp was installed as the rear license plate lamp. From 1945 to 1947, the minimum required external lamps have been finalized. Qualified car lights should meet the corresponding luminosity, chromaticity and basic environmental test specifications.
