What changed
  • In paragraph 7.1., the rule for a headlamp that provides bend lighting now names UN Regulation No. 149 without the words “classes A, B or D of”.
  • Paragraphs 7.3.1. and 7.3.2. no longer list the approval markings of the headlamps.
  • Footnote 4 now says “right-hand traffic” and “left-hand traffic” instead of “right-hand driving” and “left-hand driving”.
Why
  • The proposal aims to cover all passing beams (AFS or not) of the 00 and 01 series of UN Regulation No. 149.
  • The wording aims to minimise future changes and to correct missing references to the latest UN Regulation No. 149 series in paragraphs 7.3.1. and 7.3.2.
  • Footnote 4 must apply to the point 50R (L) only, and its wording is aligned with UN Regulations Nos. 48 and 149.

Q1What changed6 changes

Headlamps that provide bend lighting (para. 7.1.)

A headlamp (UN Regulations Nos. 98, 112 or 149) providing bend lighting must be set for the test in a straightforward direction. Before this supplement, the text said “UN Regulation No. 98 or 112 or classes A, B or D of UN Regulation No. 149”. The words “classes A, B or D of” are removed.

The efficiency of the cleaner shall be tested in accordance with the requirements of Annex 4 to this Regulation. The cleaning efficiency at the points on the measuring screen which are specified below shall, after every cleaning period, amount to at least 70 per cent for the principal passing beam lamp and also 70 per cent for the optional driving lamp; in case of an AFS this provision applies to the photometric test procedures as defined in Annex 9 to UN Regulation No. 123 or in Annex 4 to UN Regulation No. 149 from those lighting units in the neutral state indicated in paragraph 6.1.1. above. In the case of a headlamp (UN Regulation NoRegulations Nos. 98 or , 112 or classes A, B or D of UN Regulation No. 149) providing bend lighting, the headlamp shall be set for the test in a straightforward direction.

Approval markings removed (paras. 7.3.1. and 7.3.2.)

Paragraph 7.3.1. now reads “Headlamps approved in respect of the passing beam only”, without the markings “C or HC or XC/V/E/W/T in the approval mark”. Paragraph 7.3.2. now reads “Headlamps approved in respect of the passing beam and the driving beam”, without the markings “CR, HCR, C+R, C+HR, HC+R or HC+HR or XC/V/E/W/R/T”.

Headlamps approved in respect of the passing beam only (marking C or HC or XC/V/E/W/T in the approval mark); ;
Headlamps approved in respect of the passing beam and the driving beam (marking CR, HCR, C+R, C+HR, HC+R or HC+HR or XC/V/E/W/R/T)..

Measuring points and footnote 4

The line “Measuring points: 50 R (L) and 50 V.” now reads “Measuring points: 50R (L) and 50V.”. The line “Measuring points; 50R (L) (and 50V if in the same headlamps …” now reads “Measuring points; 50R (L) and 50V, if in the same headlamps …”. Footnote 4 now says that R refers to right-hand traffic and L refers to left-hand traffic. Before, it said “driving” instead of “traffic”.

Measuring points: 50 R 50R (L) and 50 V50V.
Measuring points; 50R (L) (and 50V , if in the same headlamps, different optical systems for the driving beam and the passing beam are provided.

Q2Why it changed

Proposed by
Experts from the International Automotive Lighting and Light-Signalling Expert Group (GTB)
Working party
GRE, 89th session (October 2023)

Reasons

  • The proposal aims to cover all passing beams (AFS or not) of the 00 and 01 series of UN Regulation No. 149. It also makes some corrections.

    Sources (2)
    “with the aim to integrate all passing-beams (adaptive front-lighting systems (AFS) or not) of UN Regulation No. 149 series 00 and 01 and to make some corrections”
    “that covered all passing beams (AFS or not) of the 00 and 01 series to UN Regulation No. 149 and made corrections”

  • The proposal intends to remove the list of classes in paragraph 7.1. In paragraphs 7.3.1. and 7.3.2., it intends to refer in a more general way only to passing beams and driving beams. One aim is to minimise future changes. The other aim is to correct the missing references to the latest series of amendments to UN Regulation No. 149 in those paragraphs.

    “this proposal intends to remove the list of the classes concerned in paragraph 7.1. and to refer, in a more general way, only to passing-beams and driving-beams in paragraphs 7.3.1. and 7.3.2.”
