Proposal to require installation of direction indicators on mopeds.

Proposal to specify the use of UN R48 definitions unless otherwise specified in the current regulation or in lighting installation regulations for other vehicles categories (i.e., in UN R53, R74, or R86) and to otherwise clarify the text in Annex 2.

Proposal to improve the text, adds that the definitions in UN R48 apply unless the regulation or the vehicle-category-specific regulations (UN R53, 78, 86) specify different applicable definitions, to clarify that the construction provision and prohibition on use of paints or varnishes under paragraph 4.1.6 only apply to retro-reflectors, to correct the omission of Class F devices from the title of paragraph 5.4., and to add the water-resistance test (from UN R69 and R70) to Annex 7.

Proposal to correct and clarify the requirements for daytime running lamps (DRL) in conjunction with rear position lamps and to introduce requirements for light emitting diode (LED) substitute light sources.

Proposal from the IWVTA informal group concerning acceptance of Limited IWVTA approvals.

Proposal from the IWVTA informal group concerning the acceptance of Limited IWVTA approvals.

Proposal to update UN R0 in line with the restructuring of the UN lighting regulations, to introduce use of the UN on-line system for sharing information on acceptance of type approvals, and to amend the annex concerning “Specifications of the IWVTA DoC”, including replacing a reference to the type approval number with the VIN.

Proposal from the Simplification of Lighting Regulations informal group to delete the luminous intensities minimum requirements for the measuring point 50L (which are not in UN R112 and therefore should not be in UN R149) from Table 8 and to correct a typo in the angular position for S100RR in Table 13. Given its urgency, the proposal has been submitted in parallel for GRE consideration (GRE-82-02).

Proposal to align UN R50 and UN R53 regarding the inward geometric visibility requirements for rear position lamps, to allow the use of different stop lamp activation methods for powered two-wheelers as currently applicable for four-wheelers; e.g. by the application of a retarder or a similar device, and to make editorial corrections.

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

• 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 introduce new light emitting diode (LED) substitute light source categories C5W/LEDK, R5W/LED, W5W/LEDK and WY5W/LED.

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