Proposal to introduce an alternative configuration for the light emitting diode replacement (LEDr) light source category H11.

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 to correct and clarify the communication form.

Proposal to clarify the measurement of the quality of the “cut-off”.

Proposal to clarify the markings. Some countries and regions refer to the requirements of the 00 series of amendments to UN R149, or to older regulations. In order to avoid the redundant burden to mark the symbols of both the 00 and 01 series on the lamp (e.g., “HCR” or “HR and C”), the proposal would allow for consistency of the symbols between the 00 and the 01 series of amendments. UN R149 also includes passing-beam requirements designed to provide symmetrical “cut-off” line: the proposal introduces examples in Annex 13.

Proposal to enable the approval under UN R74 of a front and rear indicator that can be activated simultaneously, to allow the installation of optional direction indicators at national level on bicycles (including vehicles with a maximum design speed not exceeding 25 km/h), and to introduce a new symbol “-“ under UN R148 between the symbols indicating the functions of the device in order to differentiate a device which fulfils the requirement of a front indicator of category 11 and a rear indicator of category 12 that cannot be activated simultaneously from one that can.

Proposal to address lamp positioning on wider vehicles of categories R, S, and T, to allow using reflective materials as an alternative to retro-reflectors, to clarify provisions (including failure detection), and to make editorial improvements.

Proposal from the Autonomous Vehicles Signalling Reguirements (AVSR) task force to update the text of UN R48 to enable application to vehicles equipped with an Automated Driving System (ADS).

Proposal to address vehicles of categories R or T with a width more than 2.55 m and of category S with a width more than 3 m as well as to allow using reflective materials as an alternative to retro-reflectors.

Proposal from the EMC informal group to update electromagnetic radiation immunity provisions, address automatic emergency call systems (AECS) and automated driving systems (ADS), update references to standards, and effect editorial improvements.

Informal document submitted by the Task Force on Substitutes / Retrofits (TFSR) to support and proposal changes to formal proposal GRE/2024/2.

LUPC task force mandate to review the requirements of the current suite of lamps under parked conditions and to develop, where necessary, proposals to address the energy indicator and lamp test mode under UN R48.

Proposal from the AVSR task force to amend its earlier document.

Revised 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.

Interpretation question on the provision “With the exception of retro-reflectors, a lamp even bearing an approval mark is deemed not to be present when it cannot be made to operate by the sole installation of a light source and/or a fuse.”

Proposal to enable the approval of a front and rear indicator which can be activated simultaneously. This informal document supersedes the formal proposal GRE/2024/9.

Proposal to introduce the provisions to enable the use of light-signalling in form of projection of patterns on the road for other road users through new light-signalling functions “Direction indicator projection” and “Reversing projection”.
