Draft proposal to introduce into Regulation No. 48 a definition and general requirements for usage of a “change index” established by the new simplified Regulations on Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD). The “change index” indicates the number of times new series of amendments have posed higher stringency requirements to a specific lamp (function) under these regulations.

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.

Additional questions from Poland to OICA for clarification the expectations concerning 1.6% cut-off inclination limits range as a result of non-repeatability of vehicles according Reg. 48 load/pitch test (Annex 5 and 6).

Currently, interpretations of electrical connection requirements for headlamps, lamps of paragraph 5.11 and daytime running lamps differ between Contracting Parties. In general, this working draft proposal being prepared by the Task Force on Headlamp Switching aims to clarify the requirements.

Clean version of the VGL informal group justification for the proposed headlamp aiming tolerance diagram with corrections and new appendices II and III as proposed by T.Targosinski.

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.

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?

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 for provisions concerning headlamp switching.

Updated version of the OICA proposal including corrections proposed by Italy.

Proposal to clarify that dipped-beam headlamps may not be switched OFF manually when they have been switched ON automatically according to paragraph 6.2.7.5., except in the case specified in paragraph 6.2.7.5.1. Manual switching OFF of headlamps at night should be limited to exceptional cases specified in the regulation. This proposal clarifies that daytime running lamps shall not be switched OFF except as specified in paragraphs 6.19.7.1. to 6.19.7.6.

Draft proposal for definitions of “assembly”, “function”, and “headlamp” for application across the new UN lighting device regulations.
