Pursuant to interpretation issues raised by Germany at the seventy-fifth session of GRE, a Task Force on Sequential Activaton was established to clarify the meaning of the “one continuous line” requirement in paragraph 5.6.(c) of Regulation No. 6. The task force proposes to clarify the type definition and reduce the need for dividing sequential direction indicators into different types. This proposal revises the text to be more technology-neutral, removing specifications on how light sources are activated to focus on the visual performance as sequential lighting. The amendment of sub-paragraph 5.6.(c) of UN R6 clarifies what kind of vertical movement is not allowed in the sequential direction indicators, proposing a new new term “vertical oscillations” instead of the current wording “repeating alternation in the vertical direction”. The meaning is that not more than one change of direction upwards or downwards along the vertical axis is possible. The “continuous signal” is also defined in sub-paragraph 5.6.(c) of Regulation No. 6. The allowed distance between adjacent or tangential distinct parts has yet to be defined. TF-SA could not find a consensus about the distance (in mm) before the deadline for submitting official working documents to the seventy-sixth session of GRE. Thus, the value is still marked between square brackets, leaving the final decision to GRE. Before the seventy-sixth session of GRE, TF-SA experts are going to investigate what the suitable value would be. The idea of TF-SA is that the sequential direction indicator should produce a visually clear and continuous signal when viewed by an observer from a 10 m distance. The same amendments as in paragraph 5.6. of the UN R6 are also proposed to paragraph 6.8. of Regulation No. 50 for L-category vehicles. Unlike paragraph 1.3. of Regulation No. 6, paragraph 2.2. of Regulation No. 50 does not define the sequential activation as a type differentiation criterion. Therefore, amendments to paragraph 2.2. of Regulation No. 50 are not necessary.

Paragraph 6.5.3. of UN R48 prescribes the use of specific categories of front direction indicators in relation to their distance from the dipped beam headlamp or front fog lamp. However, the text allows categories 1a and 1b to be used at any distance greater than the minimum prescribed for each of them. The present text of UN R6, Annex 1, however, only allows a specific category to be used in the specific range of distance prescribed. Therefore, this proposal deletes the specific requirements in UN R6 and introduces a direct reference to the requirements in UN R48. This proposal effectively eliminates the need for a lower maximum value for the Category 1 front direction indicator than that of the other categories. Therefore, it is proposed to align the maximum luminous intensity value of Category 1 to that of Categories 1a and 1b.

Proposal to align the text of paragraph 6.1.6. with the definition of “single lamp” introduced by document ECE/TRANS/WP.29/GRE/2014/6 (Proposal for Supplement 14 to the 04 Series of amendments, Supplement 7 to the 05 Series of amendments and Supplement 5 to the 06 Series of amendments of Regulation No. 48). The reference to paragraph 4.2.2.6. in the header of the table in paragraph 6.1. is also corrected.

Supplement 11 to the 02 series of amendments to Regulation No. 7 introduced a new paragraph “0. SCOPE” that included vehicles of category “L”. This proposal corrects the title of the Regulation, removing the exception of motor cycles.

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.

Supplement 3 to the 01 series of amendments to UN R 98, 112, and 123 deleted the measurement point HV from the photometric requirement table. The HV measurement point, however, remains a requirement for checking photometric stability. This proposal removes the HV measurement point from the photometric stability requirements for the passing beam. The HV measurement point remains a valid for the driving beam.

Proposal to add a new paragraph 3.6.2.4. to UN R99 in order to clarify how the run-up of dual-level high-intensity discharge (HID) light sources, as e.g. D9S, should be tested during type approval. In addition, the proposal renumbers the part of 3.6.2.2. that applies to gas-discharge light sources containing black stripes as 3.6.2.3. to make the distinction with gas-discharge light sources not containing black stripes.

The content of paragraph 7.5. was moved to Annex 3, paragraph 3.3. by supplement 4 to the 01 series of Regulation No. 119. The original content of paragraph 7.5. should have been deleted as part of the amendment, but this was overlooked. This amendment is necessary to remove the current conflict between the content of Annex 3, paragraph 3.3. and paragraph 7.5 in the main text.

During its 69th session, GRE adopted proposals to update the Conformity of Production (CoP) procedures for lighting and light-signalling devices, but decided to await the work of a GTB task force on the simplification of CoP provisions for AFS before addressing UN R123. This proposal amends the CoP procedures in line with those agreed for UN R112 (document GRE/2013/37) to create simplified photometric CoP tables for each class (C, V, W, E, R, RADB) with its applicable 0/20/30 per cent limits. Furthermore, the task force clarified which tests are necessary for CoP testing and which are necessary only for type approval testing. The methods and requirements for the “initial” type approval remained unchanged. An overview of the main AFS characteristics can be found in documents GRE-48-28 and GRE-48-30.

When the 01 series of amendments to Regulation No. 123 was introduced to convert the photometric requirements from illuminance E (lux) to luminous intensities I (cd), some changes from E_max to I_max were overlooked. This amendment introduces the necessary corrections. The proposal also amends Annex 3, Table 2 to allow sub-classes of Class C to lower the cut-off position to give the opportunity to adapt to foggy weather conditions and thus avoid glare and increase safety.

This proposal removes the requirement to indicate the rated wattage in the marking of lamps equipped with electronic light source control gear and/or non-replaceable light sources and/or light source module(s). From an electronic point of view, the information of the wattage brings no benefit and is confusing if the same module is used in different systems and at different wattages.

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.

This collective amendment on the stability of photometric performance during the heat test, with particular reference to the movement of the cut-off line, clarifies the test cycle and also aligns the requirements of Regulations Nos. 19, 98, 112, 113 and 123. In addition to resolving problems of interpretation presented by the current text, this collective amendment will assist the Informal Working Group “Simplification of Lighting and Light-Signalling Regulations” in drafting the new simplified Regulations which is underway.

Proposal to amend Regulation No. 48 following the outcome of the 167th session of the World Forum where amendments to Regulations Nos. 97 and 116 on the status indicators for Vehicle Alarm System (VAS), Alarm System (AS) and immobilizer were adopted (WP.29/2015/87 and WP.29/2015/91). The proposal aims at defining and specifying the operation of the external status indicator for VAS, AS and the immobilizer.

This collective amendment extends the usage of LED light sources of UN R128 to front lighting Regulations Nos. 19, 98, 112, 113 and 123 (as presented in the previous session document GRE-75-14). The proposal would allow for the use of regulated replaceable LED light sources according to Regulation No. 128 in all applications where the use of LED modules is already permitted.

Motorcycle daytime running lamps (DRL) can cause glare under nightime conditions (i.e., if left activated after sunset). Therefore, this proposal would require automatic switching from DRL to normal headlamp lighting as conditions warrant.
