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.

Proposal from the Simplification of Lighting Regulations informal group to combine provisions of UN Regulations Nos. 4, 6, 7, 23, 38, 50, 77, 87 and 91 into a single regulation. This consolidation aims to streamline the administration and implementation of these lighting regulations while setting the foundation for a future shift towards performance-based approval requirements. This proposal restructures the existing body of lighting regulations without changing their content (e.g., technical requirements).

Proposal from the Simplification of Lighting Regulations informal group to consolidate common definitions of terms concerning lighting, light signalling, retro-reflective devices and device installation into Regulation No. 48. (Definitions specific to particular devices would be maintained in the respective device regulations.)

Proposal 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 Electromagnetic Compatibility to align UN R10 with the International Special Committee on Radio Interference (CISPR) 12 Standard vehicle narrow-band limit and the last CISPR 12 set-ups (artificial networks, harness location, Z-folding, …) for vehicles in charging mode.

Proposal from the Simplification of Lighting Regulations informal group to introduce transitional provisions for the phasing out of the existing Regulations on lighting and light-signalling in conjunction with the introduction of three new simplified Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD).

Proposal to introduce the following changes into the draft new Regulation on light-signalling devices:

1. Use of LED substitute light source(s) is allowed and does not constitute a change of the lamp type. However, lamp performances shall be tested during type approval also with the LED substitute light source. Approval of the lamp using filament light source(s) is a prerequisite for approval of the lamp using LED substitute light source(s).
2. COP testing of the lamp is required with an (etalon) filament light source only, because the LED substitute is the counterpart light source of the filament light source, resulting in equivalent photometrical lamp performance. The quality i.e. the equivalence to the filament light source, is controlled in R128.
3. Use of LED substitute light sources is at the discretion of the applicant, who shall declare this use, if any, to the Approval Authorities at the time of application for the first lamp approval or subsequent extension of approval issued for the version using the LED substitute light source.
4. The use of LED substitute light source(s) in a certain lamp type shall be indicated on the lamp by marking of the LED substitute light source category, in addition to the marking of the filament light source of which the LED substitute light source is the counterpart.
5. This marking on the lamp will be used for checking the allowance for use of lamps with LED substitute light sources in application of the Regulation on lamps installation on vehicle.
6. In case a lamp with colour filter(s) is approved for using LED substitute light source(s), this lamp shall be marked “G” to indicate that this lamp shall be equipped with LED substitute light source(s) marked “G” for colour and luminous intensity quality reasons.
7. The indication of both the filament light source and of its LED counterpart light source, if any, shall be explicitly provided in the communication form.

Proposal to introduce requirements for replaceable light-emitting diode (LED) light sources for forward lighting in the new Regulation on Road Illumination Devices (RID). As the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) continues working on the new RID Regulation, it is not possible to indicate all detailed modifications that will be required to incorporate the replaceable LED light sources for forward lighting. However, in general, only simple editorial changes will be required. Further work is required to identify the changes that will be required in the annexes.

Proposal to introduce a new light emitting diode (LED) forward lighting light source category L1/6. The proposal is part of a package which also includes amendments to Regulation No. 128. 2. GTB proposes one category L1/6 with “maximum test temperature” 65 °C. The definition of the maximum test temperature is necessary to ensure interchangeability between approved light sources from different manufacturers. A separate (unique) light source category is specified for every “maximum test temperature”. The choice of installation of a light source with a given maximum test temperature is based on the application in the vehicle and determined by due diligence of the car maker and set maker, in the same way as is now the case with LED modules.

Proposal to introduce new light-emitting diode (LED) substitute light source categories C5W/LED, PY21W/LED and R5W/LED. This proposal is part of a package which also includes amendments to Regulation No. 128.
