Introduction to Headlight Colors

Americans love to personalize their vehicles. Since the launch of Henry Ford's Model T in 1908, car owners have been customizing their cars. However, when it comes to headlight colors, there are rules to follow.

Federal Motor Vehicle Safety Standards

The National Highway Safety Bureau was created in 1966 to reduce traffic accidents. The first Federal Motor Vehicle Safety Standards (FMVSS) were introduced in 1968. Section 571.108 of the FMVSS outlines regulations for vehicle lighting, including headlamps. The only allowed colors for headlights are white and yellow, and they must be uniform.

State and Local Regulations

While the FMVSS is nationwide, state and local regulations vary. For example:

  • California allows white and yellow headlights
  • Michigan, Oklahoma, and Texas only allow white headlights
  • Florida and Ohio allow white or amber headlights
  • New York prohibits headlight modifications that change the original design or performance

Tinting headlights is prohibited in most states, except Arizona. However, Arizona still requires headlights to be white or yellow and visible from a distance.
