UN Regulation No. 149.

GRE is invited to address proposals that were prepared by the expert from GTB with
the aim to amend failure detection and signalization requirements to reflect technological
progress in multiple light sources. These proposals were submitted in a package with
corresponding amendment proposals to UN Regulation No. 48.

GRE/2024/18 | UN R149: Proposal for a Supplement to the 00 and 01 series of amendments This proposal intends to rectify the inconsistency between UN Regulation No. 149, (both original version and 01 series of amendments) and the frozen UN Regulations (namely UN Regulations Nos. 98, 112 and 123) by aligning the measurement points for the mechanical deterioration test. The deletion of measuring point HV, for the passing-beam headlamps, does not change any technical requirement since there are no photometric values specified for point HV in the UN Regulation No. 149, both in the original version and in the 01 series of amendments.

GRE-91-19 | UN R149: Proposal for a Supplement to the 01 series of amendments Proposal aims to correct COP Tables. the maximum luminous intensity of Segment BLL for Class V (see Tables 6 and 7) was intentionally changed from 880 cd (as in UN Regulation No. 123 and in the original series of amendments of UN Regulation No. 149) to 625 cd (as in the 01 series of amendments to UN Regulation No. 149). The purpose of this modification was to align the value with Class C but, by mistake, this change was not reflected in the COP Tables 25 and 26

GRE/2024/22 | UN R149: Proposal for a Supplement to the 01 series of amendments 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 isdetected 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

GRE-91-04 | UN R149: GTB analysis of the Chinese questions on interpretation Chinese questions submitted at the 90th GRE session (doc. GRE-90-29)

available.

GRE/2024/16 | UN R65: Proposal for Supplement 13 Proposal to correct and clarify the existing provisions. The proposal aims to allow Category HT and X special warning lamps emitting light in different colours in the same manner as Category T.

GRE will recall that, at its previous sessions, it had adopted the following amendments
but had decided to postpone their submission to WP.29, in order to combine them with future
amendment proposals to the same UN Regulation and series of amendments:
• GRE-88-17 and ECE/TRANS/WP.29/GRE/2023/13 as a Supplement to the 03, 04
and 05 series of amendments to UN Regulation No. 48;
• ECE/TRANS/WP.29/GRE/2024/3 as a Supplement to the 06, 07, 08 and 09 series of
amendments to UN Regulation No. 48;
• ECE/TRANS/WP.29/GRE/2024/4 as a Supplement to the 06, 07, 08 series and the 09
series of amendments to UN Regulation No. 48;
• GRE-90-10 as a Supplement to the 09 series of amendment to UN Regulation No. 48;
and
• GRE-90-36 as a Supplement to the 06 series of amendments to UN Regulation No.10.

GRE-88-17 | UN R48: Proposal for Supplements to the 03 through 08 series of amendments Proposal to align UN R48 from the 03 to the 08 series of amendments with 01 series of amendments to UN Regulations Nos.148 and 149.

GRE/2023/13 | UN R48: Proposal for a Supplement to the 06, 07, 08 [and 09] series of amendments Proposal to correct a reference to the 01 series of amendments to UN Regulation No. 148.

GRE-90-10 | UN R48: Proposal superseding document GRE/2024/5 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.

GRE/2024/3 | UN R48: Proposal for a Supplement to the 06, 07, 08 and 09 series of amendments 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.

GRE/2024/4 | UN R48: Proposal for a Supplement to the 06, 07 and 08 series of amendments 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.

GRE-90-36 | UN R10: Proposal for a corrigendum to 06 series of amendments Proposal for modification of Markings and Conformity of production

GRE-91-15 | UNN R10: Status update by IWG EMC (Electromagnetic Compatibility)

At the previous session, the expert of the Fédération Internationale de l’Automobile
(FIA) presented the results of their 2024 European consumer study on glare in road traffic.
To tackle this issue, some GRE experts spoke in favour of establishing a task force (TF),
while one expert felt that an informal working group (IWG) would be more appropriate.
Without taking a decision, GRE invited interested parties to discuss this issue, and to prepare
for the present session draft terms of reference and rules of procedure for either a new TF or
new IWG.
