Proposed list of UN Regulations applicable to IWVTA Phase 2 (2018 – 2022).

Proposal to clarify and simplify the original text.

The document was prepared by the GRE-IWG SLR to show the latest status of work and collect feedback from GRE for the preparation of the final proposal that will be submitted to the 83rd GRE session.

Japan basically agrees with the proposal made by Germany but considers that certain points need clarification.

Proposal to restore the sequential activation of direction indicators of categories 11, 11a, 11b, 11c and 12, which were included in UN Regulation No. 50 but omitted when UN R148 was developed during SLR Stage 1. The corresponding references to UN Regulation Nos. 53 and 86 have been included.

Proposal to differentiate light source modules in cases where a signalling device contains more than one different module. The proposal adds the missing provision for multiple light source modules that is present in paragraph 3.6.2. of UN R7 and should be transposed into this regulation.

Proposal to correct an error in the figure in Annex II, A3-X based on the original figure taken from UN R4, Annex 3 (b).

Proposal to include daytime running lamps in the provision for ‘an assembly of two independent lamps to be type approved as lamp marked “D”’.

Proposal to improve the proposal submitted by the experts from France and Germany to allow under specified conditions the use of manufacturer logos inside the illuminant surface of a signalling lamp.

Proposal to restore the correct value for the vertical visibility angle requirement.

This proposal is aimed at restoring the correct value for the vertical visibility angle requirement in the original proposal for UN Regulation No. 148.

Proposal to

• clarify paragraph 2.1 with regard to definitions: “All the definitions given in the latest series of amendments to UN Regulation No. 48 in force at the time of application for type approval shall apply, unless otherwise specified in this UN Regulation or in the pertinent installation UN Regulations Nos. 53, 74 and 86.”
• amend the inboard visibility angle for rear position lamps in pairs in the new UN Regulation on Light-Signalling Devices (LSD)
• 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).
• Testing with LED substitute light sources is exempted from conformity of production control.
• The technical description shall include notice that the lamp also has to be approved with the LED substitute light source(s) according to UN R128 if the applicant has so determined.
• The approval marking or the Unique Identifier as well as the category or categories of LED substitute light source(s) prescribed, if any, shall be visible.
• The indication of both the holder of the filament light source and of its LED counterpart light source, if any, shall be explicitly provided.
• Introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd.

Proposal to remove differentiation of the categories for direction indicators as they are bound to the Installation Regulations and to clarify the text regarding the assignment of horizontal or vertical angles to individual lamps.

Proposal to allow the use of logos inside the illuminating surface of a signalling lamp under certain conditions.

Proposal from the Simplification of Lighting Regulations informal group to delete a footnote indicator and delete characters from a figure on the standard light distribution of devices.

Proposal to introduce requirements for testing the sun load impact, which can delay the perception of a signal in such a way that it may became a serious safety issue, if the sun load impact goes above a defined ratio.

Revision of document SLR-29-04/Rev.1.

Comments on the proposal to introduce requirements for testing sun-load impact.

Proposal to allow under specified conditions the use of logos inside the illuminating surface of a signalling lamp.

Proposal to introduce requirements for testing the sun load impact to avoid delays in the perception of light signals under certain sunlight conditions.
