Discussion paper concerning modifications to the draft proposal for a new UN Regulation on road illumination devices in order to achieve the aims of GRE/2016/34 which proposed amendments to Regulations 19, 98, 112, 113 and 123.

Request to delete the amendment to paragraph 3.3.4.1.1. in the proposal to introduce requirements for the use of light-emitting diode substitute light sources in the new Regulation on Light-Signalling Devices. The proposed amendment was included in the submission by mistake.

The proposal opens the opportunity to project driver assistance symbols on the road ahead the vehicle as part of the Adaptive Driving Beam by introducing angular limits for the placement of these projections as well as luminous intensity limits in order to guarantee a good perceptibility of the symbols for the driver at night time without distracting other road users.

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

Proposal to extend to AFS passing-beam headlamps the possibility to project driver assistance symbols and patterns if the pertinent requirements of UN R149 are fulfilled.

Proposal to introduce requirements for replaceable light-emitting diode (LED) light sources for forward lighting in the new Regulation on Road Illumination Devices (RID). As the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) continues working on the new RID Regulation, it is not possible to indicate all detailed modifications that will be required to incorporate the replaceable LED light sources for forward lighting. However, in general, only simple editorial changes will be required. Further work is required to identify the changes that will be required in the annexes.

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 insert a new paragraph 3.2.5. corresponding to paragraph 4.4. in UN R119 which was unintentionally omitted from the original text of UN R149.

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

Proposal to correct the Conformity of Production (CoP) values in Tables 26, 27, 28 and 29.

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

Proposal to remove the failure mode and light source failure detection requirements for the cornering lamp.

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.

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.

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

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 correct the numbering within paragraph 4.11. and to clarify the CoP provisions in Annex 8.

Proposal to clarify the marking requirements for headlamp functions.

Proposal to improve the accuracy of the instrumental aiming method.

Proposal to clarify the 80% failure criterion for Conformity of Production (CoP) checks by confirming that CoP tables represent a simplified subset of the full Class C type-approval measurement points, and to exclude overhead requirements (items S50 and S100 in Tables 6 and 7) from the passing beam failure detection criterion, as these may be fulfilled by position lamps. Further details can be found in informal document GRE-94-08.

Proposal to improve the clarity and structure of Conformity of Production (CoP) requirements for driving beams in UN R149 by following the approach used in UN R123.

Proposal to correct inconsistencies and calculation errors in Conformity of Production (CoP) tables across both series of UN R149, which may otherwise cause confusion for manufacturers and technical services.

In UN R149-00, corrections include: deletion of erroneous maximum values at point 50L in CoP tables for Classes C, V and W Bend Light; correction of miscalculated 20% and 30% CoP minimum values for Classes C and V Bend Light Category 1; correction of the Class W non-bending mode maximum value at Segment 10 and its derived CoP values; and correction of rounding errors in Class R CoP minimum values.

In UN R149-01, corrections include: updating the Class W Bend Light CoP maximum at point BR to align with the type-approval table; correcting miscalculated Class R Bend Lighting CoP values; and fixing table note references in Annex 4 following the introduction of scientific notation in the 01 series.

Further details can be found in informal document GRE-94-10.
