Proposal to enable the optional use of hazard warning lamps on L1 category vehicles to alert other vehicles in case of breakdown or other situations that could lead to danger on the road.

This proposal brings L1 category warning signal options in line with those for other 2-wheeled vehicles.

Text prepared by the International Motorcycle Manufacturers Association (IMMA) to introduce the possibility of interdependent lamps for dedicated motorcycle lamps. The proposal reflects recent amendments of Regulations Nos. 6 and 7 and meets the visibility angle requirements of Regulations Nos. 50 and 53. The concern is that the rear trunk lid commonly used for four-wheeled vehicles may be adapted for future scooter type motorcycles to secure the storage space for helmet, etc. Current lamp requirements impose design constraints that may hamper the proper development of such storage features.

Text prepared by the expert from the International Motorcycle Manufacturers Association (IMMA) to introduce the possibility of installing interdependent lamps for L3 category vehicles. Also, the amendment reflects the recent amendments to Regulation No. 48, Supplement 2 to its 06 series of amendments and further includes some editorial corrections of current Regulation No. 53 texts. The concern is that the rear trunk lid commonly used for four-wheeled vehicles may be adapted for future scooter type motorcycles to secure the storage space for helmet, etc. Current lamp requirements impose design constraints that may hamper the proper development of such storage features.

Text submitted by the International Motorcycle Manufacturers Association (IMMA) to allow for the use of different brake lamp activation methods for Powered Two Wheelers (PTWs). This amendment also introduces the concept of a high-mounted stop lamp to PTWs to improve the conspicuity of the vehicles during stopping.

Text prepared by the International Motorcycle Manufacturers Association (IMMA) to correct typographical errors introduced during previous amendment to the regulation (ECE/TRANS/WP.29/2012/83). The initial changes were already in Revision 2 of UN Regulation No. 113.

Revised proposal (superseding document GRE/2014/7) to introduce the possibility of interdependent lamps for dedicated motorcycle lamps. The proposal reflects recent amendments to Regulations Nos. 6 and 7 and meets the visibility angle requirements of Regulations Nos. 50 and 53. The concern is that the rear trunk lid commonly used for four-wheeled vehicles may be adapted for future scooter type motorcycles to secure the storage space for helmet, etc. Current lamp requirements impose design constraints that may hamper the proper development of such storage features.

Revised proposal (superseding document GRE/2014/8) to allow for the installation of interdependent lamps for L3 category vehicles. The amendment also reflects recent amendments to Regulation No. 48, Supplement 2 to its 06 series of amendments and further includes some editorial corrections of current Regulation No. 53 texts. The concern is that the rear trunk lid commonly used for four-wheeled vehicles may be adapted for future scooter type motorcycles to secure the storage space for helmet, etc. Current lamp requirements impose design constraints that may hamper the proper development of such storage features.

Proposal to enable the approval of sequential activation of light sources of direction indicators lamps for motorcycles.

Proposal to delete the angle of incidence provision that was developed to ensure that the vehicle registration plate is illuminated. Given current technologies (e.g., LED lamps), the performance requirements of Annex 5 can be met without reference to the angle of incidence.

Proposal to allow for the installation on motorcycles of light-signalling devices with light sources that can be sequentially activated.

Proposal to enable the approval of emergency stop signal on motorcycles to increase safety.

Proposal to delete references to UN R113 Class B headlamps from the regulation.

Proposal to allow the use of different brake lamp activation methods and to align the brake lamp provision with those applicable for four-wheelers.

Proposal to update the definition of “stop lamp” (in line with similar definitions in UN R7 and UN R48) so that it would allow the use of different stop lamp activation methods for powered two-wheelers (e.g. by the application of a retarder or a similar device). A corresponding proposal for amendments to Regulation No. 78 (GRRF/2017/14) has been submitted to the September 2017 session of the Working Party on Braking and Running Gear.

Proposal to remove the prohibition against lamps “reciprocally incorporated” with any other lamp. This proposal would align UN R53 with UN R48 and correct an oversight from a previous amendment process.

Proposal to explicitly allow direction indicators to be activated when the motorcycle engine is stopped in order to signal the vehicle status. Some motorcycles currently offer this feature; however, it is not clear whether the scope of Regulation No. 53 covers and allows this function.

Proposal to clarify the text with regard to the activation of the direction indicators when the motorcycle engine in order to signal the vehicle status. The proposal would specify the purposes for which indicators may be activated:

1. To show the vehicle status (e.g. locking system) when the vehicle is parked;
2. To allow the driver to recognize the presence of his/her own vehicle from a certain distance by remote control;
3. In case of keyless entry system and of the driver having lost the key fob while riding – to inform the driver that he/she no longer has the key fob and that the vehicle will soon become unable to restart.

Proposal to allow installation of exterior courtesy lamps on motorcycles by aligning the text with provisions on courtesy lamps in UN R48.

Proposal to align the angle of visibility requirements for rear position lamps with the angle of visibility requirements for front position lamps. This proposal corresponds with a related proposal on Regulation No. 53 (GRE/2018/28).

Proposal to align UN R50 and UN R53 regarding the inward geometric visibility requirements for rear position lamps.

Proposal to update the definition of “stop lamp” in order to allow the use of different stop lamp activation methods for powered two-wheelers as currently applicable for four-wheelers; e.g. by the application of a retarder or a similar device.

Proposal to clarify conditions under which direction indicator lamps may be switched ON to indicate the status of the device to prevent unauthorized use.

Proposal to include provisions for exterior courtesy lamps on motorcycles under UN R53 (as is already the case for motor vehicles under UN R48).

Proposal to restore the original automatic headlamp ON (AHO) requirement for vehicles not equipped with daytime running lamps (DRL). The 03 series of amendments (focusing on DRL) as approved by GRE during its October 2018 session (document GRE/2018/50) changes provisions for automatic headlamps as adopted for motorcycles in 2004 (see document GRE/2003/12/Rev.1). While appropriate for vehicles equipped with DRL, the changes would reduce safety for vehicles not equipped with DRL.

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).

Proposal aim to allow the installation of Adaptive Driving Beams (ADB) on vehicles of category L₃.

Proposes to clarify the electrical connection requirements for a white front position lamp reciprocally incorporated with the front direction indicator.

Proposal to enable the use of Rear-End Collision Alert Signal (RECAS) on vehicles of category L₃.

roposal to expand the application of glare-free Adaptive Driving Beam (ADB) for category L₃ motorcycles under UN R149, by introducing additional driving beam classes aligned with UN R53 motorcycle requirements and adding symmetrical passing beam-based photometric requirements below the H-H line (Table 13, Part C). Recent technological advances have made ADB electronics more practical for a broader range of motorcycles, and these amendments aim to enhance traffic safety by reducing glare while maintaining adequate rider visibility.
