This information report is being issued to cover conversions from inch-pound units to those in the System International (SI) approach. Since all conversions cannot possibly be covered, the list contained in Section 4 is composed of the lighting oriented items which are found in SAE or Motor Vehicle Safety Standard (MVSS) in North America. This reference is to FMVSS in the United States and to CMVSS in Canada. The purpose of this report is to give guidance for uniformity particularly to those organizations, governmental or otherwise, who may in the future have occasion to express present inch-pound units in metric or SI terms.
The Lighting Systems Steering Committee reports to the Motor Vehicle Council (MVC). This systems group acts as the "parent" committee for all the following Lighting committees. Lighting Discussion Forum Heavy-Duty Lighting Standards Committee Lighting Materials Standards Committee Road Illumination Devices Standards Committee Signaling and Marking Devices Standards Committee Test Methods and Equipment Standards Committee Emergency Warning Lights and Devices Standards Committee International Lighting Standards Committee Lighting Standard Practices Committee. The Lighting Discussion Forum was created to ensure all Lighting committee members and mail list participants have easy access to general lighting information. Participants in the SAE Lighting Systems Group iinclude current chairpersons from each Lighting committee as well as past chairs employed by OEMs, suppliers, consulting firms, government, and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
