Test Methods and Equipment for Lighting Devices and Components for Use on Vehicles Less than 2032 mm in Overall Width
This SAE Recommended Practice provides standardized laboratory tests, test methods, and requirements applicable to many of the lighting devices and components covered by SAE Recommended Practices and Standards and is intended for reference for devices used on vehicles less than 2032 mm in width, regardless of length, or 7620 mm in length regardless of width. Tests for vehicles larger than 2032 mm in overall width are covered in J2139.
Rationale:Revision for test voltageWith the adoption of electronic controlled light sources along with bulbs for lighting devices, a consisted voltage measurement technique must be defined. This revision is to specify where in the lighting system the test voltage measurement should be taken for repeatability during testing.
