Limited Adaptive Forward Lighting System
This SAE Recommended Practice applies to motor vehicle Forward Illumination Devices which incorporate limited adaptive beam pattern capabilities. This document is to be used in conjunction with other forward lighting standards and/or recommended practices which define the base beam procedures, requirements, and guidelines.
Title, Scope – Added term “Limited” to document title and scope to further distinguish this document from SAE J2838 – Full Adaptive Forward Lighting Systems.
2.1, 2.2 – Updated format wording.
2.1.1, 2.2.1 – Moved SAE J575 to Applicable Documents section and revise title.
2.2.1, 2.2.2, 2.2.3, 2.2.4 – Updated and corrected reference titles.
3.5 – Removed references to variables that can influence the beam pattern, since these variables are not addressed in the document.
