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.

In document GRE/2014/7, IMMA proposed to introduce the possibility of interdependent lamps for dedicated motorcycle lamps as Supplement 17 to Regulation No. 50. The concern was 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. In this document, India proposes to clarify that the installation height of the device must be less than or equal to 750 mm.

Correction to the proposal for Supplement 17 to Regulation No. 50 (to introduce the possibility of interdependent lamps for dedicated motorcycle lamps). Annex 1, Paragraph 4., should read: “However, in the case where a device is intended to be installed with its H plane at a mounting height less than 750 mm above the ground, the angle of 15 10° below the horizontal may be reduced to 5°”

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.

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.
