This SAE Recommended Practice provides general design performance requirements and related test procedures for LED “white” lighting unit assemblies, other than signal and marking devices, used on Earthmoving, Road Building, and Maintenance off-road work machines as defined in SAE J1116. This report is intended to serve as a guide to standard practice and is subject to change to reflect additional experience and technical advances.
Rationale
Many lighting devices are now using LED light sources for signaling and marking applications. These light sources now have performance equaling or greater than the incandescent and halogen light sources previously used. With this technology being employed, it is reasonable to address this usage in machine work lamps with recommended practice in the design of a LED light source device. Photometric Tables 2 and 3 have been taken from SAE J598 as being reasonable and applicable to the general trapezoid and flood patterns used for work illumination on this equipment.
This document is cross-referenced with SAE J2121; therefore, both documents should be published at the same time.
OPTC3 addresses standards related to sounds, lighting and marking for off-road, self-propelled work machines, and equipment. This committee reports to ConAg Council through OPTC. ConAg Council covers machines described in SAE J1116 which includes machines defined in ISO 6165, ISO 6814, and ISO 22242, with regards to activities supporting; • Creating consensus SAE standards, recommended practices, and information reports • Harmonizing relevant SAE documents with ISO documents • Assisting the US with the creation and maintenance of ISO standards through US TAGs o ISO/TC 127 --- Earth-moving machinery o ISO/TC 195 --- Building construction machinery and equipment o ISO/TC 23/SC 15 --- Machinery for forestry Participants in this committee include OEMs, suppliers, consulting firms, government, and others across the construction and forestry industries.
* 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.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
