Rationale: The Lighting Systems Steering Committee agreed to merge SAE J2040 into SAE J585. In general, there is a large amount of redundancy in these two documents and there was a desire to merge the document for vehicles equal to or greater than 2032 mm in overall width with the document for vehicles less than 2032 mm in overall width. SAE J2040 will become obsolete when the merged SAE J585 document is published. There will be a reference when SAE J2040 is searched that will direct users to SAE J585. Updates to this revision include: Document title revised to include lamps on vehicles less than, equal to, and greater than 2032 mm in overall width. Table of contents revised. Section 1: Scope revised to include lamps on vehicles less than, equal to, and greater than 2032 mm in overall width. 2.1.1: Added SAE J2139 test document reference for vehicles greater than 2032 mm in overall width. 2.1.1: Moved SAE J2040 from 2.2.1. 2.1.1: SAE J578 “Color Specification” changed to “Chromaticity Requirements.” 2.2.1: Removed reference to SAE J2040. 2.2.1: Removed reference to SAE J567 and SAE J2139. 2.2.1: SAE J567, SAE J1330, and SAE 830566 documents added. 2.2.1: SAE J1319 moved from 2.1 to 2.2. 2.2.3: “ECE” changed to “UN.” 2.2.3: UN R148 added. 2.2.4: Section and publications added. 3.1: Tail light function definition added. 3.1: Tail lamp definition revised (now 3.2). 3.3: Revised, formatting. 3.3: “Tail lamp function” changed to “tail light function.” 3.4: Removed “Tail lamp arrangement means all the elements or components that comprise the tail lamp function.” 4.0: “T” and “T2” tail lamp codes identified and defined. 5.1: “Are applicable” inserted in sentence after “SAE J2139.” 5.1: Wording revised to be analogous to 6.1. 5.1.5.2: Edited to include lighting identification codes T and T2 type lamps. 5.1.5.2: Corrected grammar by removing “are” from sentence to read: “… the photometric requirements specified …”. 5.2: Revised from “… shall be determined by SAE J578” to “… shall be tested according to SAE J578.” Table 1: Title and content revised. 6.1: Added reference to SAE J2139. 6.1.5.1: Revised for clarity. 6.1.5.2: Revised for clarity. 6.1.5.3: Revised for clarity. 6.1.5.4: Revised for clarity.
