PROPOSAL FOR SUPPLEMENT 8 TO THE 01 SERIES OF
AMENDMENTS TO
REGULATION NO. 123
(ADAPTIVE FRONT-LIGHTING SYSTEMS (AFS))
ADOPTED AT THE 171 SESSION – MARCH 2017
PROVISIONAL DATE OF ENTRY INTO FORCE: OCTOBER 10, 2017

Paragraph 5.7.3., amend to read:
"5.7.3. In the case of failure it must be possible to obtain automatically a passing beam or a state
with respect to the photometric conditions which yields values not exceeding 1,300cd in the
zone III b as defined in Annex 3 to this Regulation and at least 3,400cd in a point of
"segment I ", by such means as e.g. switching off, dimming, aiming downwards, and/or
functional substitution;
When performing the tests to verify compliance with these requirements, the Technical
Service responsible for approval tests shall refer to the instructions supplied by the
applicant."
Paragraph 6.2.4., amend to read:
"6.2.4. When emitting a specified mode of the passing beam, the system shall meet the
requirements in the respective section (C, V, E, W) of part A of Table 1 (photometric values)
and in Table 2 I and "cut-off" positions) of Annex 3 to this Regulation, as well as
Section 1 ("cut-off" requirements) of Annex 8 to this Regulation."
Paragraph 6.2.5.4., amend to read:
"6.2.5.4. If approval is sought for a category 1 bending mode, the system is designed so that, in the
case of a failure affecting the lateral movement or modification of the illumination, it must be
possible to obtain automatically either photometric conditions corresponding to
Paragraph 6.2.4. above or a state with respect to the photometric conditions which yields
values not exceeding 1,300cd in the Zone IIIb, as defined in Annex 3 to this Regulation, and
at least 3,400cd in a point of "segment I ";"
Paragraph 6.4.3.1, amend to read:
"6.4.3.1. Passing beam: points B50L and 75R, or 50R if applicable;
Driving beam: I and point HV (percentage of I );"

Table 2, amend to read:
"Table 2
Passing Beam Elements Angular Position/Extend, Additional Requirements
"
Annex 4,
Introductory Part, amend to read:
"Tests for Stability of Photometric Performance of Systems in Operation - Tests on Complete
Systems
Tests on Complete Systems
Once the photometric values have been measured according to the prescriptions of this Regulation, in
the point of I for driving beam and in points 25L, 50V and B50L (or R), whichever applies for passing
beam, a complete system sample shall be tested for stability of photometric performance in operation.
…"
Paragraph 1.2.1.2., amend to read:
"1.2.1.2. For a system or parts thereof with the outside lens in plastic material, the mixture of water
and polluting agent to be applied to the test sample shall be composed of:
(a)
(b)
9 parts by weight of silica sand with a particle size of 0-100μm,
1 part by weight of vegetal carbon dust produced from beech wood with a particle
size of 0-100μm,
(c) 0.2 part by weight of NaCMC ,
(d) 5 parts by weight of sodium chloride (pure at 99%),

Annex 5,
Paragraph 1.2.1.1., amend to read:
"1.2.1.1. For the following values of the passing beam and its modes, the maximum unfavourable
deviation may be respectively:
(a) Maximum values at point B50L 170cd equivalent 20% and 255cd equivalent 30%;
(b)
(c)
Maximum values at Zone III and segment BLL: 255cd equivalent 20% and 380cd
equivalent 30%;
Maximum values at segments E, F1, F2 and F3: 170cd equivalent 20% and 255cd
equivalent 30%;
(d) Minimum values at BR, P, at the groups S 50 + S 50LL + S 50RR, S 100 + S 100LL +
S 100RR, and those required by Footnote of Table 1 in Annex 3 of this Regulation
(B50L, BR, BRR, BLL): half of the required value equivalent 20% and three quarter of
the required value equivalent 30%."
Paragraph 2.4., amend to read:
"2.4. Measured and Recorded Photometric Characteristics
Annex 6,
The sampled headlamps shall be subjected to photometric measurements at the points
provided for in the Regulation, the reading being limited:
To points I , HV , "HL" and "HR" in the case of a driving beam,
To points B50L, 50L, 50V, 75R if applicable, and 25LL in the case of the passing beam(s)
(see Figure 1 in Annex 3)."
Paragraph 2.1.2.1., amend to read:
"2.1.2.1. Method
Photometric measurements shall be carried out on the samples before and after the test.
These measurements shall be made according to Annex 9 to this Regulation, at the
following points:
B50L and 50V for the class C passing beam lighting;
I for the driving beam of a system."
Paragraph 2.6.1.2., amend to read:
"2.6.1.2. Results
After the test, the results of photometric measurements carried out on the system or part
thereof in accordance with this Regulation shall not exceed by more than 30% the maximum
values prescribed at point B50L and not be more than 10% below the minimum values
prescribed at point 75R, if applicable."
