This SAE Standard provides test procedures, performance requirements, and guidelines for semiautomatic headlamp beam switching devices.

This SAE Standard provides test procedures and performance requirements for spot lamps.

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.

This technical report covers performance requirements, design requirements, and design guidelines for replaceable bulbs which may be used in headlamp applications.

The Society of Automotive Engineers 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 significant reduction in the recommended maximum height at which headlamps, particularly lower beam headlamps, may be mounted. Heights as low as 36 to 40 in (0.9 to 1.0 m) 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.

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 designed with light sources other than LED sources.

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.

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 nighttime 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.

This document applies to the requirements of a device used in the field and inspection stations to aim and check aim of mechanically aimable headlamp units. The purpose of this document is to provide a laboratory test procedure to determine whether the devices under test are capable of accurately positioning headlamp units from their aiming pads and maintaining their accuracy in service within the tolerances designated in this document.
