Proposal to introduce variable daytime running lamps into the regulation.

Proposal to introduce new criteria on the automatic leveling of headlamps based on GTB glare and visibility studies. This proposal is for formal consideration and advice from Contracting Parties, with the expectation that a finalized text will be submitted for adoption at the seventy-fourth session of GRE.

Proposal for Supplement 17 to the 04 series of amendments, Supplement 10 to the 05 series of amendments and Supplement 8 to the 06 series of amendments to Regulation No. 48. The proposal seeks to clarify paragraph 6.21.1.2.4. with regard to the application of conspicuity markings on bodywork made of flexible material.

Proposal to further refine the transitional provisions of UN R48. In 2014, the transitional provisions of UN R48 were changed in order to avoid having more than one series of amendments in force at the same time (via Supplement 3 to the 06 series of amendments). This change allows earlier series of amendments to be “frozen” and used under the International Whole Vehicle Type Approval system (IWVTA) as “versions” of UN R48. However, the possibility for the partial application of a series of amendments resulting from the installation of new equipment on a vehicle approved to an earlier series has been raised within the IWVTA. This proposal refines the transitional provisions in order to enable partial application of a series through an extension of the existing approval rather by requiring a new approval. At the same time, the proposal aims to ensure that the safety objectives of UN R48 are met.

Proposal to correct the terminology in paragraph 5.7.2.1. for consistency across all requirements and to clarify the language in paragraphs 6.2.9., 6.3.6.1.2.1. and 6.3.6.1.2.2. to promote the correct application of the 2,000-lumen limit.

The current requirements on light source failure in lamps equipped with multiple light sources differ across UN Regulations. GTB submitted and then withdrew a proposal to align these requirements (GRE/2016/13). This updated proposal improves upon the text of the previous proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.

Proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.

Proposal to enable approval of side-marker and position lamps with regard to switching requirements when mutually incorporated. Vehicles include designs where lamps wrap around vehicle corners. In cases where optional side-marker lamps are grouped with a position lamp that is reciprocally incorporated with the direction indicator, it should be possible to switch off the side-marker lamp (as can be done with the position lamp) in order to improve conspicuity of the direction indicator.

Proposal to introduce technical parameters for speed and vehicle distance in order to encourage reduced glaring effects from rear signaling lamps. The proposal allows for reduced intensity at speeds lower than 20 km/h.

Proposal to allow the projection of driver assistance symbols on the road ahead of the vehicle as part of the Adaptive Driving Beam (ADB).

Proposal to allow driver assistance projections on the road ahead of the vehicle as part of the Adaptive Driving Beam (ADB).

Proposal to clarify determination of the apparent surface.

Proposal by the experts from GTB with the aim to allow driver assistance projections, on the road ahead of the vehicle, as part of the Adaptive Driving Beam (ADB). It also proposes same supplement for R149.

Proposal to remove the minimum distance between the left and right front/rear position lamps.

Proposal to correct and clarify the failure provisions.

Proposal for corrections to the text.

Proposal to clarify and standardize the usage of flashing side marker lamp to all types of vehicles.

Proposal to correct and clarify the provisions for matched pairs.

Proposal to extend to AFS passing-beam headlamps the possibility to project driver assistance symbols and patterns.

Proposal to allow the projection of a pattern for predicted trajectory.

Proposal to extend to AFS passing-beam headlamps the possibility to project driver assistance symbols and patterns

Proposal to clarify usage of daytime running lamps (DRL) with other lamps.

Proposal to improve the definition of photometric stability.

Proposal to align the requirements in UN R48 with updated requirements in UN R149 (UN R48 currently only refers to a light source or light-emitting diode (LED) module(s) for dipped beam (paragraph 6.2.9.) and to light sources of the lighting units for an adaptive front-lighting system (AFS) (paragraph 6.22.9.) while the latest updates to the 01 series of UN R149 requires the communication form to indicate whether the total objective luminous flux of one or more light source(s) or light source module(s) for a dipped beam exceeds 2,000 lumens). This proposal replaces the term “LED module” with “Light source module” and modifies wording to adapt to the introduction of “matched pair” requirements for headlamps and AFS.

Proposal to align the requirements for off-road vehicles passing-beam vertical inclination between the 06, 07, 08 series and the 09 series of amendments to UN R48.

Proposal to avoid exceeding the aggregate maximum intensity of the main-beam headlamps (430,000 cd) by removing the double requirement for a sum of reference marks and a sum of maximum luminous intensities which risks generating large rounding errors when the maximum luminous intensities are summed up.

Proposal with the aim to allow the projection of a pattern for predicted trajectory.

Proposal aims to introduce Direction Indicator Projections. This proposal intends to introduce the possibility of light-signalling, in form of projection of patterns on the road, for other road users through new light-signalling function “Direction indicator projection”.

Proposal aims to amend failure detection and signalisation requirements to reflect technological progress in multiple light sources. This amendment proposes to include in UN Regulation No. 149 different provisions allowing that a failure signal is only triggered when a significant change in the beam is detected and ensuring that the most suitable failure provision can be applied. Proposal for a Supplement to the 06, 07, 08 and 09 series of amendments to UN Regulation No. 48

Proposal to allow the installation of side-marker lamps combined with retro-reflectors on the lateral foremost position on semi-trailers.

Proposal to clarify the duration of the optical indication of the answer-back signal.

Proposal to clarify the voltage requirements for light-emitting diodes (LED).

Proposal to clarify and modernize lamp installation and component requirements in UN R48 and UN R148:

• Remove the “band/strip” terminology and expand the definition of a pair of lamps to cover full-width designs
• Remove the three-device maximum for Y-lamps to ensure technology neutrality
• Add a new paragraph §5.5.5 defining a pair as a two-lamp system
• Relocate light source requirements from UN R48 to UN R148 §4.7.3 to ensure at least one light source per side
• Remove the 0.8-metre minimum length requirement
• Clarify that definitions in §2.4.10 apply only to the relevant vehicle categories
• Update provisions for light source positioning in UN R148
• Clarify §4.8.1.3 in UN R148
• Add new sampling provisions in §4.8.11 for testing band/strip lamps

Proposal to exclude retro-reflective devices and markings from the requirement of “Red light to the front” and “White light to the rear”.

Proposal to introduce selective yellow as an permitted alternative to white for front position lamps and daytime running lamps in UN R48 and UN R148. Studies confirm that selective yellow performs equally to white for oncoming vehicle recognition and speed estimation. Unlike historical filament lamp applications where a yellow filter reduced luminous intensity, modern LEDs achieve the same intensity levels without reduction. Specific amendments include: updating §5.15 to reflect selective yellow options and removing a duplicated front fog lamp requirement; amending §§6.9.7 and 6.19.7 to deactivate selective yellow position and daytime running lamps on the relevant side during direction indicator activation; and aligning UN R148 (01 series) by amending §§5.1.7, 5.4.7 and Annex 1 accordingly. The colour boundaries for selective yellow are already defined in §2.11.1.2 and require no amendment. Further details can be found in informal document GRE-94-05.

Proposal to align the Exterior Courtesy Lamps provisions of the 08 series amendments with those of the 09 series.

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