Proposal for Supplement 20 to Regulation No. 50
Document WP.29/2017/81
11 April 2017

Proposal to clarify the provisions for sequential activation of direction indicator lighting, especially concerning the interpretation of the phrase “one continuous line”. The proposal, developed by a special task force, clarifies the type definition and reduces 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 is limited 50mm (which differs in this case from UN R48 specifications). Transitional provisions have been included.

7. (a) | Regulation No. 6 (Direction indicators)

22. On behalf of the Task Force on Sequential Activation (TF-SA), the expert from Finland reported on its activities and proposed to clarify the requirements for direction indicators with sequential activation in Regulations Nos. 6 and 50 (ECE/TRANS/WP.29/GRE/2016/20 and GRE-76-10). The proposals received written comments from the experts of France, India and OICA (GRE-76-05, GRE-76-09 and GRE-76-16). Following an extensive discussion, GRE adopted the amended proposals, as laid down in Annex IV. At the same time, GRE was not in a position to reach consensus on whether or not the proposals would require a new series of amendments and/or transitional provisions. GRE decided to come back to this issue at the next session in April 2017. Meanwhile, the secretariat was requested to issue the adopted text (Annex IV) as a document for the June 2017 session of WP.29, upon the understanding that any possible amendments, to be decided by GRE in April 2017, could exceptionally be submitted to WP.29 as a corrigendum or addendum to this document.

7. (d) | Regulation No. 50 (Position, stop, direction indicators lamps for mopeds and motorcycles)

26. GRE noted that the proposal to clarify the requirements for direction indicators with sequential activation (ECE/TRANS/WP.29/GRE/2016/20) was considered in conjunction with Regulation No. 6 (para. 22 above).
