SAE Lighting Identification Codes

SAE J759

SAE International stands for the International Society of Automotive and Aerospace Engineers.

They provide the standards that all vehicle safety products must adhere to.

As you can see, they identify the type of equipment by a letter/number code for each product group.

Use this information in conjunction with the Federal Lighting Equipment Location Requirements for each product shown on our FMVSS Requirements page.
