Q2Why it changed

Proposed by
Informal Working Group on Simplification of Lighting and Light-Signalling Regulations (IWG SLR)
Working party
GRE, 88th session (April 2023)

Reasons

  • IWG SLR prepared the text with the aim to enable the phasing out of the installation of older lamps and devices. The proposal is based on the initial request by the expert of the European Commission at the 85th GRE session. The request was to modify the transitional provisions of the new 01 series of amendments to UN Regulations Nos. 148, 149 and 150.

    Sources (3)
    “with the aim to enable the phasing out of the installation of older lamps/devices”
    “This proposal is based on the initial request by the expert of the European Commission at the eighty-fifth session of the Working Party on Lighting and Light-Signalling (GRE)”
    “to modify the transitional provisions of the new 01 series of amendments to UN Regulations Nos. 148, 149 and 150”

  • IWG SLR agreed that the most practical way was to prescribe the 01 series changes in the lighting installation regulations. In particular, they go into the individual specifications of each function (paragraph 6). The European Commission requested to specify which device regulations, and which series of amendments, are allowed for each single function in installation regulations. The proposal reflects this request.

    Sources (3)
    “IWG SLR agreed that the most practical way to introduce changes made to the 01 series of the UN Regulations Nos. 148, 149 and 150 was to prescribe them in lighting installation regulations”
    “the European Commission requested to specify which device regulations (and their corresponding series of amendments) are allowed for each single function in installation regulations”
    “This proposal reflects the request by the European Commission.”

  • An IMMA analysis showed that the main technical changes of the 01 series were in UN Regulation No. 149. These changes were for road illumination devices, namely all classes of passing-beam and driving-beam headlamps. Allowing only headlamps approved to the 01 series of No. 149 implies phasing out a number of headlamp classes that are nowadays widely used. This increases the stringency of UN Regulation No. 74, so a new 03 series with transitional provisions is necessary.

    Sources (4)
    “the International Motorcycle Manufacturers Association (IMMA) conducted an in-depth technical analysis of the new requirements introduced by the 01 series of the three UN device Regulations”
    “it was evident that the main technical changes were introduced into UN Regulation No. 149 for road illumination devices, namely all classes of passing-beam and driving-beam headlamps”
    “The proposed amendments will result in allowing only the installation of headlamps approved to the 01 series of UN Regulation No. 149, which implies phasing out a number of headlamp classes which are nowadays widely used.”
    “Such a restriction increases the level of stringency of UN Regulation No. 74, and it is therefore necessary to create a new 03 series with its corresponding transitional provisions.”

  • The words “and extensions thereof” were added to paragraph 12.10.4. for clarification, to avoid different interpretations of the conditions. This was a specific request of the expert from the European Commission.
