Dimensional Specifications for General Service Sealed Lighting Units

2017-11-16
CURRENT
J3003_201711
This SAE Recommended Practice provides dimensional specifications for the 41/2 and 53/4 inch 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.

Discharge Forward Lighting System and Subsystems

2005-10-03
HISTORICAL
J2009_200510
This SAE Recommended Practice applies to motor vehicle forward illumination systems and subsystems generated by discharge sources. It provides test methods, requirements, and guidelines applicable to the special characteristics of gaseous discharge lighting devices which supplement those required for forward illumination systems using incandescent light sources. The document is applicable to both discharge forward lighting systems, subsystems and components. This document is intended to be a guide to standard practice and is subject to change to reflect additional experience and technical advances.

CURRENT
J1606_201102
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.

Improved Roadway Illumination: Information Resource

2011-04-14
CURRENT
J2738_201104
Headlamps should illuminate the traffic scene ahead of the vehicle in such a way that the driver can operate the vehicle safely and in a relaxed manner. At the same time, negative effects on drivers of other vehicles, pedestrians and other people should be minimized. Various technical parameters such as beam pattern, mounting height, headlamp aiming, and source spectrum can be tuned to find the necessary compromise. The physiology of the vision system under specific night time conditions strongly influences these factors and how headlamps can be best optimized for visibility and comfort. The SAE Improved Roadway Illumination task force collected and reviewed relevant research on these topics. This document is a comprehensive summary of this information. The goal is to enable lighting experts, advocacy groups, and non-experts (journalists, consumer organizations, car drivers) to better understand the benefits and tradeoffs of improved roadway lighting with modern headlamp technology.

Pedestrian Visibility - Low Beam Optimization to Reduce Night-time Fatalities

2011-02-24
CURRENT
J2829_201102
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.

HISTORICAL
J2650_200509
This SAE Recommended Practice provides performance requirements, test procedures, and design and installation guidelines for road illumination devices that incorporate light emitting diode (LED) modules. These requirements are in addition to those specified for devices deisnged with light sources other than LED sources.

Recommendations of the SAE Task Force on Headlamp Mounting Height

2011-02-24
CURRENT
J2338_201102
The SAE International task force on headlamp mounting height has considered the ramifications of reducing the maximum mounting height of headlamps on highway vehicles. The task force has concluded that it is in the best interest of the driving public to make a substantial reduction in the recommended maximum height at which headlamps, particularly low-beam headlamps, may be mounted. Heights as low as 36 to 40 in (90 to 100 cm) have been considered. New tractor vehicles are in fact being designed with headlamps mounted in this range. Further recommendations were withheld in anticipation of tests to demonstrate the effect of mounting height on the legibility of certain overhead signs.
