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.

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.
