Submission of the International Motorcycle Manufacturers Association (IMMA) in order to change the inward visibility angle of front position lamp in Regulation No. 50.

Proposal to revise the Italian proposal in order to clarify that the requirements pertain only to characteristics verifiable directly on each lamp in order to avoid confusion with characteristics that can only be verified on the vehicle after installation.

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.

Updated document to correct the original proposal to introduce the possibility of interdependent lamps for dedicated motorcycle lamps by including an omitted diagram and highlighting the marking clause.

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.

Clarification of certain diagrams in the original proposal (document GRE/2014/15). Supplement 17 proposes to introduce the possibility of interdependent lamps for dedicated motorcycle lamps.

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

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).

In response to discussions over the application of Revision 3 to the 1958 Agreement concerning extensions of approvals granted prior to Revision 3, IMMA presents an example from UN R50 where application of Revision 3 presents concerns.
