Updated paper on the grouping of lighting regulations under one of three new regulations as follows:
Light Signaling Devices incorporating Regulations 4, 6, 7, 23, 38, 50, 77, 87, and 91
Forward Lighting Devices incorporating Regulations 19, 98, 112, [ 113 ], 119, and 123
Retro-Reflective Devices incorporating Regulations 3, 27, 69, 70, and 104

Proposal to align the text in the header row of the table in paragraph 6.1 (light emitted by the lamps) with the definitions used in Regulation No. 48 for the installation of “single lamps”, “lamps marked D” and “interdependent lamps”.

Compressed data package of three documents providing lists of proposals for amendments to lighting regulations within the context of plans for the restructuring of UN lighting regulations.

Request for interpretation on approvals of LED direction indicators integrated with daytime running lamps and using sequential activation of horizontal bars. Germany proposes a task for on sequential activation of direction indicators to develop clear provisions within the regulation, especially with regard to paragraph 5.6 (c): sequential activation … shall be one continuous line with no repeating alternation in the vertical direction.

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.

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 justification for changes to sub-paragraphs 5.6.(e) of Regulation No. 6 and 6.8.(e) of Regulation No. 50 is missing from document GRE/2016/20. The Task Force on Sequential Activation of direction indicators wishes to note that the paragraphs were proposed by GTB and accepted by the Task Force to clarify the text without changing the current technical requirements.

GTB proposal for incorporation of the DETA Universal Identifier approval mark into the UN Regulation on direction indicators.
