SAE (Society of Automotive Engineers) is a worldwide organization that sets automotive standards for the manufacturing, testing, and design of car lightings. DOT (Department of Transportation) is the federal agency that set standards for car lightings. In short, SAE guide the quality of the product, and DOT test the product to make sure it is fully complied with transportation law and approve for use in all US roads and highways.
