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.

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.

Request for guidance regarding interpretation of UN lighting rules:

1. Is it allowed that the shape of the apparent surface can be the logo of the manufacturer brand or other brand-identifying figures?
2. Is it allowed that the shape of the apparent surface can be the same as an evocative/suggestive figure? Even as an informative figure such as road traffic
   signs?
3. Is the advertising lighting allowed at the national level in the Contracting parties, regarding to its influence on road safety and distraction?
4. Do we have to consider an apparent surface, whose shape is the logo of a brand manufacturer or other brand-identifying figures, as a advertising lighting?

Request to delete the amendment to paragraph 3.3.4.1.1. in the proposal to introduce requirements for the use of light-emitting diode substitute light sources in the new Regulation on Light-Signalling Devices. The proposed amendment was included in the submission by mistake.

Proposal to address inconsistencies, clarify text, and correct terminology in Regulation No. 48:

• para. 5.7.2.1. editorial alignment of text with current terminology
• replace undefined “effective outlet” terminology with defined “apparent surface” reference
• reintroduction of missing reference to “transverse plane” in paras. 5.10.1. and 5.10.2.
• para. 6.2.9. and related subsequent paragraphs to clarify the application of the 2000 lumen criteria
• para. 6.26.9.2. to correct a cross-reference with UN R23.

Proposal to reinsert text in paragraph 1.3 concerning differentiation of types according to trade name or mark that was inadvertently omitted from Supplements 27 and 28 to the 01 series of amendments.

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 from the EMC task force to delete obsolete transitional provisions from UN R10 and introduce additional transitional provisions for the 05 series of amendments (e.g., covering five-year period during which Contracting Parties must accept vehicles approved to the 04 series and after which parties may refuse vehicles that do not comply with the 05 series). The proposal also requires Contracting Parties to continue accepting non-electrified vehicles (i.e., vehicles without battery charging systems) previously approved to the 03 or 04 series of amendments even after the five-year transitional period.

Proposal to correct HIR2 headlamp data.

Revised proposal, superseding document GRE/2017/11, from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into Regulation No. 48.

Proposal from the Task Force on Headlamp Switching to clarify requirements for electrical connections for headlamps, daytime running lamps, and related lighting devices.

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 for new headlamp aiming tolerances from the informal group on Visibility, Glare, and Levelling.

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 to replace figures in the original proposal.

Japan comments on manual switching off of headlamps during night conditions and the relationship between DRL and front position lamps.

Headlamp switching task force working draft with possible amendments to UN R48 pursuant to GRE-78-21/Rev.1.

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