| UN R48: Proposal for a Supplement |
| Reference Number: GRE/2020/2 |
|
Proposal to add a reference to the installation parameters of the licence plate illumination lamps determined during their type approval process. Every type-approved device or pair of devices have their own geometrical position in relation to the rear registration plate which is determined based on the illumination levels, maximum gradient value, angles of visibility and light incidence angle. This proposal would introduce a reference to these parameters in UN R48. |

| Draft new Regulation on uniform provisions concerning the approval of light-signalling devices |
| Reference Number: GRE/2017/9 |
|
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). |

| Rear registration plates with LED |
| Reference Number: GRE-76-12 |
|
Advances in LED lighting raise the prospects for incorporation of lighting into rear registration plates. In 2004, in response to a proposal for the regulation of such plates under UN R48, GRE determined that illuminated plates were not lamps and therefore were outside the scope of UN R48. The Spanish delegation would like to submit this issue again for the consideration of GRE members in order to have a coordinated and common view on this subject. |

|
This proposal removes the requirement to indicate the rated wattage in the marking of lamps equipped with electronic light source control gear and/or non-replaceable light sources and/or light source module(s). From an electronic point of view, the information of the wattage brings no benefit and is confusing if the same module is used in different systems and at different wattages. |

| Explanation of the proposal to amend UN Regulation No. 4 on rear registration plates |
| Reference Number: GRE-70-38 |
|
As part of the work on establishing an International Whole Vehicle Type Approval (IWVTA) system, Japan has noted differences between European and Japanese vehicle registration (license) plates. Since UN R4 would be part of the IWVTA process, Japan seeks to add its plate requirements to the European requirements embodied in UN R4 in order to enable Japan to adopt this regulation and thereby adhere to the IWVTA. |
