Revised proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.

Review prepared by the Task force on Substitute and Retrofit Light Sources chair.

Comments collected by GRB in response to the proposals to prevent misuse of replacement lamps (GRE/2017/17, GRE/2017/22, GRE-78-28) during the 78th GRE session.

Changes to the proposal to introduce LED light sources into the lighting installation Regulations Nos. 48, 53, 74 and 86.

Two part proposal to a) make the fitting of front position lamps optional and b) allow for its separate control under certain conditions and for rear positions lamps and registration plate lamps to be lit during the period between the activation of the master switch and the engine start.

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.

Proposal to introduce new references to the new lighting device regulations developed under the Simplification of Lighting Regulations program. This informal proposal is for information and review with the references in brackets.

Explanation of changes between the proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86 presented at GRE-77E/2017/4) and the revised proposal (GRE/2017/22) submitted for consideration at GRE-78.

Proposal to align the draft Supplement 20 to the 01 series of amendments and draft Supplement 2 to the 02 series of amendments to UN R53 more closely with UN R48. These supplements concern the use of different stop lamp activation methods (in alignment with similar provisions for four-wheeled vehicles).

Proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.

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.

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.

Proposal to make the fitting of front position lamps optional and allow for its separate control under certain conditions and to allow for rear positions lamps and registration plate lamps to be lit during the period between the activation of the master switch and the engine start.
