Proposal to require automatic switching of motorcycle daytime running lamps to headlamp illumination at night. The concern is that DRL are left on, causing glare. This proposal aligns with the provisions of UN R48.

39. The expert from Japan proposed to automatically switch from the daytime running lamp (DRL) to the headlamp at night. The experts from Austria, France, Germany, India, Netherlands, UK and IMMA commented on the proposal. GRE encouraged all experts to study the proposal and to provide their comments, if any, by the end of June 2016. GRE also invited the expert from Japan to take these comments into consideration and to submit an official document to the next session.

During April 2016, Japan presented a study to GRE-75 on the disturbance due to the use of motorcycle daytime running lamps (DRL) at night (see GRE-75-09). A proposal (GRE/2016/35 supported by GRE-76-03) for automatic switching between DRL and headlamps was then presented during October 2016 at GRE-76. Italy, among others, raised a reservation. This document details Italy’s concerns with the proposal by Japan.

24. The expert from Japan provided additional explanations to their proposals for the 03 series of amendments to Regulation No. 53 regarding a new requirement for automatic switching from DRL to the headlamp (ECE/TRANS/WP.29/GRE/2016/35 and GRE-77-19). The experts from India and Italy commented on the proposals (GRE-77-09 and GRE-77-17).

25. The experts from Italy, Netherlands and IMMA requested more time to study the proposals and comments. The expert from EC recalled that this matter had already been considered at three consecutive sessions of GRE without a conclusion. He called for the establishment of a task force to tackle the issue. The experts from Japan, India, Italy, Netherlands and IMMA expressed their willingness to participate in the task force. GRE hoped that it would be able to finalize the consideration of the proposals at the next session without establishing a task force. To this end, the Chair urged all experts to study the proposals and provide their comments prior to the next session.

31. Due to lack of time, GRE did not consider ECE/TRANS/WP.29/GRE/2017/26, ECE/TRANS/WP.29/GRE/2017/27, GRE-77-08, GRE-77-09, GRE-77-17, GRE-78-22 and GRE-78-24.

40. GRE noted that GRE-77-09, GRE-77-17 and GRE-78-22, which had not been addressed at the previous sessions due to lack of time, had been superseded by other proposals considered at this session.

Proposal from the special interest group of experts for DRL-L to introduce requirements for automatic switching from daytime running lamps (“DRL”) to headlamp(s) if maximum luminous intensity of DRL is above 700 cd.

31. Due to lack of time, GRE did not consider ECE/TRANS/WP.29/GRE/2017/26, ECE/TRANS/WP.29/GRE/2017/27, GRE-77-08, GRE-77-09, GRE-77-17, GRE-78-22 and GRE-78-24.

Proposal to require automatic switching from DRL to normal headlamp lighting as conditions warrant, amending the current UN R53 as well as the proposed new UN Regulation on light-signalling devices.

34. On behalf of the Special Interest Group for DRL of L-category vehicles, the expert from Japan proposed a new requirement for automatic switching from DRL to the headlamp for L3 category (ECE/TRANS/WP.29/GRE/2018/19). The expert from India suggested deletion of the wording “passing beam” from the text (GRE-79-20). Some GRE experts supported in principal ECE/TRANS/WP.29/GRE/2018/19, but expressed concerns about the proposed introduction of a new category of daytime running lamps with the maximum luminous intensity of 700 cd. GRE invited experts to send their comments to the Special Interest Group and agreed to continue consideration of the proposal at the next session.

Proposal from the Special Interest Group on L-category vehicle daytime running lamps to introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd.

28. On behalf of the Special Interest Group for DRL of L-category vehicles, the expert from Japan presented a revised proposal that introduced a new requirement for automatic switching from DRL to the headlamp for L3 category in UN Regulation No. 53 as well as a corresponding amendment to the new LSD UN Regulation (ECE/TRANS/WP.29/GRE/2018/50). The expert from India proposed to delete references to “passing beam” (GRE-80-25). The experts of Germany, Netherlands, UK and EC were not in favour of deleting “passing beam” and supported the original proposal. GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2019 sessions as draft 03 series of amendments to UN Regulation No. 53 and draft Supplement 1 to the original LSD UN Regulation, subject to the following amendments:

Paragraphs 5.11.1.1., 5.11.1.2. and Annex 7 (twice), replace “headlamp [(passing beam)]” with “passing beam”.

Paragraphs 11.8. and 11.10., remove square brackets around 2023.

81. WP.29 noted that GRE considered and adopted a set of amendment proposals on the use of LED substitute light sources for light-signalling applications and would continue considering LED substitutes for front-lighting applications. WP.29 was also informed that GRE had adopted new series of amendments to UN Regulations Nos. 10 (Electromagnetic compatibility) and 53 (Installation of lighting and light-signalling devices for L3 vehicles).

19. The expert from IMMA recalled the draft 03 series of amendments to UN Regulation No. 53 adopted at the previous session of GRE (ECE/TRANS/WP.29/GRE/2018/50 and ECE/TRANS/WP.29/GRE/80, para. 28) and proposed to restore the original automatic headlamp requirement for vehicles not equipped with daytime running lamps (DRL) (ECE/TRANS/WP.29/GRE/2019/12). GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2019 sessions as part of the draft 03 series of amendments to UN Regulation No. 53. The expert from EC was not in a position to support the proposal.
