Proposal to require automatic headlamp activation upon start-up.

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.

Proposal to align the 03 series of amendments to UN R53 (as adopted during GRE-81: GRE/2018/50, as amended by GRE/2019/12) with the latest proposals for amendments to the 01 and 02 series (as adopted by GRE but not yet in force at the time of the present proposal:

1. Add references to UN R148, R149, and R150 (WP.29/2018/104/Rev.1 as amended by WP.29-177-07, and WP.29/2018/105), implementing the change index and amending the definitions (taking into consideration informal document GRE-80-05),
2. Align UN R53 with UN R148 regarding the inward geometric visibility requirements for rear position lamps (GRE/2018/28),
3. Clarify the use of direction indicators to show the status of the device for protection of a vehicle against unauthorised use and allow exterior courtesy lamps to be fitted on motorcycles (WP.29/2019/17 as amended by para. 107 of the session report and WP.29/2019/18 as amended by para. 108),
4. Align UN R53 with UN R48 and correct a mistake in a previous amendment process (WP.29/2018/86/Rev.1 andWP.29/2018/87/Rev.1),
5. Allow the use of different stop lamp activation methods, aligning the definition of “stop lamp” with UN R48 (GRE/2018/29), and
6. Introduce requirements for light emitting diode (LED) substitute light sources (GRE/2018/41).

35. The expert from IMMA presented a consolidated text of the draft 03 series of amendments to UN Regulation No. 53 which had incorporated the latest modifications to the 01 and 02 series (ECE/TRANS/WP.29/GRE/2019/23 and GRE-82-16). GRE noted that these modifications had been also included in the draft 03 series of amendments to UN Regulation No. 53 submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80).

Proposal to introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd and to restore the original automatic headlamp ON (AHO) requirement for vehicles not equipped with daytime running lamps (DRL) modified by the 03 series.

35. The expert from IMMA presented a consolidated text of the draft 03 series of amendments to UN Regulation No. 53 which had incorporated the latest modifications to the 01 and 02 series (ECE/TRANS/WP.29/GRE/2019/23 and GRE-82-16). GRE noted that these modifications had been also included in the draft 03 series of amendments to UN Regulation No. 53 submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80).

37. The expert from EC recalled the draft 03 series of amendments to UN Regulation No. 53, which were submitted for consideration of WP.29 and AC.1 in November 2019 (ECE/TRANS/WP.29/2019/80) and proposed to shorten its transitional period from 1 September 2023 to 1 September 2021 (GRE-82-22). The expert from IMMA pointed out the technical challenges of implementing the 03 series of amendments and suggested that the original transitional provisions should be maintained (GRE-82-37). Following an in-depth discussion, GRE decided to keep the transitional period unchanged. At the same time, GRE agreed to scrutinize all future requests for long transitional provisions by the industry.
