This SAE Recommended Practice applies to motor vehicle Distributed Lighting Systems (DLS) which use light generated by remote sources. It provides test methods, requirements, and guidelines applicable to these systems. This document is intended to be a guide to standard practice and is subject to change dependent upon additional experience and technical advances. This document covers Headlamp, Fog lamp, Auxiliary lamp, plus Signal and Marking lamp functions.

This SAE Recommended Practice provides dimensional specifications for general service sealed lighting units, intended for use in such applications as motorcycle headlamps, military headlamps, industrial machinery headlamps, fog lamps, spot lamps, etc. See Figures 1 and 2 and Tables 1 and 2.

This SAE Information Report should be used as a supplement to SAE J1383 (Reference 2.1.1). It is intended to provide additional information which is important to the automotive designer and engineer in the process of designing, developing, and engineering the headlamps of motor vehicles which will take into account the effects of the aging process on the driver.

The primary purpose of vehicle forward lighting is not to see the world but to see the road! In their simplest form, headlights help drivers negotiate a safe path on the road. They do this by lighting the roadway according to (a multitude of) specific standards. For decades, discussions concerning the niceties of illuminating potential obstacles in the roadway were little more than an academic pursuit as there simply were not sufficient lumens available from filament light sources to achieve all of the desired tasks no matter how worthy they might be. Not unexpectedly, the technology has evolved with the introduction of high output metal-halide sources, multi-task standards combined with multilevel lighting devices and discrete LED sources offering high luminous efficiencies and the means to deliver the light where it can be most useful. The question now becomes one of determining where the available light should be directed.
