Proposal to delete transitional provision subparagraphs that only apply to the 05 series of amendments to UN R48, but were erroneously kept in the 06 series of amendments.

Proposal to re-insert paragraph 5.11.1.3. with regard to switching between headlamps and DRLs. Although GRE agreed to delete this and related paragraphs during its 77th session (see para. 19 and Annex II of the 77th session report), the Task Force on Headlamp Switching decided upon further review to retain the possibility to switch ON DRLs in conjunction with at least the rear position lamps without the need for the position lamps tell-tale in that case.

Proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.

Proposal to enable approval of side-marker and position lamps with regard to switching requirements when mutually incorporated. Vehicles include designs where lamps wrap around vehicle corners. In cases where optional side-marker lamps are grouped with a position lamp that is reciprocally incorporated with the direction indicator, it should be possible to switch off the side-marker lamp (as can be done with the position lamp) in order to improve conspicuity of the direction indicator.

Proposal from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into Regulation No. 48.

Proposal from the Simplification of Lighting Regulations informal group to consolidate common definitions of terms concerning lighting, light signalling, retro-reflective devices and device installation into Regulation No. 48. (Definitions specific to particular devices would be maintained in the respective device regulations.)

Proposal as sent by the SLR informal group to GRE in order to introduce references to the proposed new lighting device regulations in UN R48.06.

Proposal for amendments as sent to GRE for consideration at its October 2017 session in order to update definitions and references in light of the new simplified architecture for lighting regulations. The text was prepared by the informal group on the Simplification of Lighting Regulations (SLR) to group the definitions of existing UN Regulations dealing with lighting, light signalling, retro-reflective devices and installation into UN Regulation No. 48, except those which are specific for a device.

Examples of loading situations and their influence on headlamp inclination cut-off.

Proposal to clarify the wording regarding the manual deactivation of headlamps. National use requirements are not harmonised and prescribe different scenarios for the use of the dipped beam headlamps. In the case where automatic activation is overridden and the headlamp switch is manually put into the ‘OFF’ position, the paragraph provides for a clear driver message that the headlamps are turned off when ambient conditions change to night time driving conditions.

Alternate version of the Headlamp Switching Task Force working draft text based upon Czech Republic and Italy proposals.

Headlamp Switching Task Force working draft based on Czech Republic and Italy proposals

Proposal to introduce definitions for the terms “activation” and “deactivation” and for “switching ON “ and “switching OFF”.

VGL informal group limit values diagram as revised by the group chair following the discussions during the 7th group session.

OICA request for changes to the (as yet unpublished) report of the 7th VGL informal group session.

Proposal to change the text of UN R48 to replace the reference to the “lower edge of the apparent surface” with a reference to the “headlamp optical centre (centre of reference)” in the passing-beam requirements.

Comments on the VGL informal group draft justification of its headlamp glare requirements.

As part of the discussions on headlamp glare and vehicle load conditions, this document provides a set of photographs illustrating various use cases where a vehicle carries a rear load.

As part of the discussions on improving UN R48 to address vehicle glare and headlamp leveling issues, Italy proposes conditions for vehicle loading under the headlamp testing procedures in order to represent more realistic vehicle use. In particular, the current specifications for testing vehicles under maximum load conditions does not represent the most common use case of a driver in an unloaded vehicle.

Commission remarks and proposals for the working draft text for a 07 series of amendments to Regulation No. 48 to address headlamp switching provisions.

Proposal to ensure that dipped-beam headlamps are not switched OFF inadvertently leaving no road illumination under dark ambient light conditions by mandating that the automatic switching ON of dipped-beam headlamps depending on the ambient light takes priority over manual switching.

Proposal to ensure that dipped-beam headlamps are not switched OFF inadvertently leaving no road illumination under dark ambient light conditions by mandating that the automatic switching ON of dipped-beam headlamps depending on the ambient light takes priority over manual switching.

Proposal to clarify and move the prohibition against the mixing of signals of two or more activation modes from UN R6/UN R50 to UN R48.

Proposal from Marcin Gorzkowski, SAE expert and former GRE chair.

Proposal to update UN R48 with regard to direction indicators and the use of sequential signaling systems.
