Q2Why it changed

Proposed by
Informal Working Group on Simplification of Lighting and Light-Signalling Regulations (IWG SLR)
Working party
GRE, 83rd session (October 2020)

Reasons

  • The proposal aims to correct the installation provisions of passing and driving beams for mopeds. It adds a reference to Class B passing beam and driving beam of UN Regulation No. 149. This reference should have been included in Supplement 11 to the 01 series of amendments. That supplement introduced references to UN Regulations Nos. 148, 149 and 150.
