roposal to expand the application of glare-free Adaptive Driving Beam (ADB) for category L₃ motorcycles under UN R149, by introducing additional driving beam classes aligned with UN R53 motorcycle requirements and adding symmetrical passing beam-based photometric requirements below the H-H line (Table 13, Part C). Recent technological advances have made ADB electronics more practical for a broader range of motorcycles, and these amendments aim to enhance traffic safety by reducing glare while maintaining adequate rider visibility.

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.

Proposal to:

• Amend Table 18 to delete maximum values at point 50L and correct minimum values at point 50L to 1,360 cd (20% CoP) and 1,190 cd (30% CoP) and delete the associated note,
• amend Table 21 to delete maximum values at point 50L and correct minimum values at point 50L to 1,360 cd (20% CoP) and 1,190 cd (30% CoP) and delete the associated note,
• amend Table 23 to correct maximum values at Segment 10 to 7,100 cd (0% CoP), 8,520 cd (20% CoP), and 9,230 cd (30% CoP),
• amend Tables 30 and 31 to correct minimum values at point HV to 25,920 cd (20% CoP) and 22,680 cd (30% CoP),
• amend Table 24 to delete the associated note regarding multiplication by 1.4,
• amend Table 28 to correct point BR maximum values to 2.65×10³ cd (0% CoP), 3.18×10³ cd (20% CoP), and 3.45×10³ cd (30% CoP),
• amend Table 29 to correct point BR maximum values to 2.65×10³ cd (0% CoP), 3.18×10³ cd (20% CoP), and 3.45×10³ cd (30% CoP),
• amend Table 35 to correct CoP minimum values at point 2U-V to 1.04×10⁴ cd (20% CoP) and 9.10×10² cd (30% CoP) and at points H-9L and H-9R to 2.16×10³ cd (20% CoP) and 1.89×10³ cd (30% CoP),
• amend Annex 4, para. 1.6.2.1. to correct references to table notes from notes 1 and 7 to notes a and f of Table 7.
