SAE J586_202405

This SAE Standard provides test procedures, requirements, and guidelines for stop lamps intended for use on vehicles of less than, equal to, or greater than 2032 mm in overall width. This standard is being reviewed as a part of SAE’s Five-Year Review policy. The Lighting Systems Steering Committee agreed to merge the Stop Lamp requirements of document SAE J2261 into document SAE J586. 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 J2261 will become obsolete when the merged SAE J586 document is published. There will be a reference when SAE J2261 is searched that will direct users to SAE J586. Updates to this revision include the following. Document title revised to include lamps on vehicles less than, equal to, or greater than 2032 mm in overall width. Table of contents revised.
