Brief presentation raising question over the necessity to have triangular reflectors on the rear of large trailers and seeking greater flexibility in such rear reflectors.

Front fog lamps may be reciprocally incorporated with the main beam and in some cases, it is required to switch off the front fog lamp when the main beam is operated to avoid overheating of the device. In this case, Regulation No. 19 requires a “/” in the approval marking. However, the current text in paragraph 6.3.7 of Regulation No. 48 requires that “it shall be possible to switch the front fog lamps ON and OFF independently of the main-beam headlamps”. This proposal is intended to remove the conflict between the texts of the two regulations.

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.

Front fog lamps may be reciprocally incorporated with the main beam and in some cases, it is required to switch off the front fog lamp when the main beam is operated to avoid overheating of the device. In this case, Regulation No. 19 requires a “/” in the approval marking. However, the current text in paragraph 6.3.7 of Regulation No. 48 requires that “it shall be possible to switch the front fog lamps ON and OFF independently of the main-beam headlamps”. This proposal is intended to remove the conflict between the texts of the two regulations. This proposal supersedes and replaces document GRE/2014/22 and has been prepared to remove ambiguities identified in the previous proposal.

Proposal to improve the applicability of paragraph 5.7.1.3.1. (concerning the separation of grouped direction indicator and stop lamps in order to avoid “signal mix”). To improve the present requirements of paragraph 5.7.1.3.1.on the basis of the colour changes concept, three alternative approaches for a suitable separation of direction indicator lamps and stop lamp are proposed:
a) the improved test of the existing paragraph 5.7.1.3.1. clarifies its application to lamps composed of more than one part and deletes the concept of “adjacent” parts of the lamps (that in the past led to different interpretations) in favour of a description of the condition of application of the requirement;
b) the unchanged text of the following paragraph 5.7.1.3.2.;
c) a new paragraph 5.7.1.3.3. to provide for specific electrical connections of the involved functions, in conjunction with the requirements of paragraph 5.9.2.

Proposal to introduce variable daytime running lamps into the regulation.

Proposal to introduce new criteria on the automatic leveling of headlamps based on GTB glare and visibility studies. This proposal is for formal consideration and advice from Contracting Parties, with the expectation that a finalized text will be submitted for adoption at the seventy-fourth session of GRE.

Supplemental presentation in support of document GRE/2015/3: Proposal for Supplement 9 to the 05 series of amendments and Supplement 7 to the 06 series of amendments to Regulation No. 48.

In November 2013, the GTB proposal for the simplification of the transitional provisions of Regulation No.48 was adopted by WP29 at its 161st session as Supplement 3 to the 06 series. Associated with this proposal was a decision that the secretariat would produce full consolidations of the 04 /05/06 series and these were introduced as Revisions 7, 8 and 9 respectively.

At that time, it was also agreed that GTB would produce a consolidation of the 03 series that would be posted on the UNECE Website for reference purposes. It was considered that a consolidation of the final (frozen) state of the 03 series would be useful as a reference for the vehicle manufacturers who may continue to apply for extensions to the original type approvals according to the 03 series. However, with the development of IWVTA and the revision of the 1958 Agreement, this consolidation may have value as “a version of a UN Regulation” as defined in the draft Revision 3.

This document is a consolidation produced by the experts of GTB and incorporates all valid text up to, and including, Supplement 5 to the 03 series of amendments (Date of entry into force: 09 December 2010). This consolidation is submitted to GRE for verification and for possible introduction to the UNECE website.

Proposal for Supplement 17 to the 04 series of amendments, Supplement 10 to the 05 series of amendments and Supplement 8 to the 06 series of amendments to Regulation No. 48. The proposal seeks to clarify paragraph 6.21.1.2.4. with regard to the application of conspicuity markings on bodywork made of flexible material.

Proposal to further refine the transitional provisions of UN R48. In 2014, the transitional provisions of UN R48 were changed in order to avoid having more than one series of amendments in force at the same time (via Supplement 3 to the 06 series of amendments). This change allows earlier series of amendments to be “frozen” and used under the International Whole Vehicle Type Approval system (IWVTA) as “versions” of UN R48. However, the possibility for the partial application of a series of amendments resulting from the installation of new equipment on a vehicle approved to an earlier series has been raised within the IWVTA. This proposal refines the transitional provisions in order to enable partial application of a series through an extension of the existing approval rather by requiring a new approval. At the same time, the proposal aims to ensure that the safety objectives of UN R48 are met.

Proposal to correct the terminology in paragraph 5.7.2.1. for consistency across all requirements and to clarify the language in paragraphs 6.2.9., 6.3.6.1.2.1. and 6.3.6.1.2.2. to promote the correct application of the 2,000-lumen limit.

The current requirements on light source failure in lamps equipped with multiple light sources differ across UN Regulations. GTB submitted and then withdrew a proposal to align these requirements (GRE/2016/13). This updated proposal improves upon the text of the previous proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.

Correction to the proposal for a collective amendment to Regulations Nos. 7, 23, 38, 48, 77, 91 and 119. Since the cornering lamp projects a beam to the left and right of the reference axis, it is not relevant to check the photometric values in the reference axis (HV). Therefore, the test point at 2.5°D, 45°L or R shall be used.

Revised proposal (removing the section on UN R48 and incorporating corrections noted in document GRE-76-07) to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required. This collective amendment addresses Regulations Nos. 7, 23, 38, 77, 91 and 119. The proposals concerning UN R48 will be resubmitted for consideration during the 77th GRE session.

Extract from the International Commission on Illumination publication “Performance Assessment Method for Vehicle Headlighting Systems”.

During October 2016, GRE-76 adopted collective amendments (GRE/2016/31) to align the requirements of lamp regulations (7, 23, 38, 48, 77, 91 and 119) to guarantee the conformity of the lamp in case of any failure or the mandatory indication that a failure had occurred. This means that when a failure indication signal is provided by the lamp, the vehicle shall be equipped with a tell-tale indicating the failure. Thus, amendments were proposed for Regulation No. 48 to specify the modes of displaying the corresponding failure (see GRE/2016/7). Subsequently, some GRE experts requested GTB to clarify the text of its proposal. This proposal amends UN R48 with respect to all lamps affected by GRE/2016/31 to include the failure indication requirement. The proposal does not apply to the failure indication requirements already in UN R 48 prior to the last (76th) GRE session.

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

Proposal to align the requirements in UN R48 with updated requirements in UN R149 (UN R48 currently only refers to a light source or light-emitting diode (LED) module(s) for dipped beam (paragraph 6.2.9.) and to light sources of the lighting units for an adaptive front-lighting system (AFS) (paragraph 6.22.9.) while the latest updates to the 01 series of UN R149 requires the communication form to indicate whether the total objective luminous flux of one or more light source(s) or light source module(s) for a dipped beam exceeds 2,000 lumens). This proposal replaces the term “LED module” with “Light source module” and modifies wording to adapt to the introduction of “matched pair” requirements for headlamps and AFS.
