Proposal to introduce type-approval provisions for lamps intended to provide supplemental lateral illumination of the road on the driver-side of the vehicle as a means to reduce the impact of glare from on-coming vehicle headlamps on driver vision and road visibility.

OICA comments on document GRE/2014/39 proposing to align UN R48 with the proposal approved by the GRSG to require the automatic activation of hazard warning lights in buses and coaches in the event of excess temperatures in the engine and/or other compartments.

Proposal to delete the requirement for automatic leveling devices for all headlamps with light emitting diode (LED) light sources based upon the results of a GTB study.

During the 71st session of GRE, the experts from GTB presented the outcome of a study on visibility and glare of automotive low beam headlamps; see informal document GRE-71-32. The study concentrated on levelling in relation to load. The major objectives of the study were to improve the understanding of different factors that influence visibility and glare and to identify results of the study that might reveal alternatives for automatic static levelling. The deciding factors in headlamp glare have been determined to be the vehicle pitch angle, loading conditions and initial headlamp aim. Therefore, this proposal looks at replacing the light source technology and the light source 2,000 lm criterion in UN Regulation No. 48 as criteria for the requirement for automatic levelling with performance requirements based upon these deciding factors.
