Proposal to rectify an inconsistency between UN R149 and UN R98, 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 R149.

Proposal to:

• Rectify an inconsistency between UN R149 and UN R98, R112 and R123 by aligning the measurement points for the mechanical deterioration test
• Correct the Conformity of Production tables
• Amend failure detection and signalisation requirements to reflect technological progress in multiple light sources.

Proposal to clarify the measurement of the quality of the “cut-off” and to clarify the approval markings under the 00 and 01 series (e.g., use of “HCR” or “HR and C”).
