have a "cut-off" with a clear "elbow", the lateral adjustment shall be affected in the manner which best satisfies the requirements for illumination at points 75R and 50R for right-hand traffic and at points 75L and 50L for left-hand traffic.
[13/] A headlamp designed to emit a passing beam may incorporate a driving beam not complying with this specification.
[14/] The limit or re-alignment of 1 degrees towards the right or left is not incompatible with upward or downward vertical realignment.  The latter is limited only by the requirements of paragraph 6.3.; however, the horizontal part of the "cut-off" should not extend beyond the line hh (the provisions of paragraph 6.3. are not applicable to headlamps intended to meet the requirements of this Regulation for the passing beam only).
[*] E50R and E50L are the illuminations actually measured.
[*/] Illumination values in any point of zones A and B, which also lies within zone III, shall not exceed 0.7lux.
[15/] Corresponding to illuminant A of the International Commission on Illumination (CIE).
[16/] This requirement will be the subject of a recommendation for the benefit of administrations.
[17/] Different values may be accepted provisionally.  In the absence of final specifications, the use of an approved headlamp is recommended.
[1/] Distinguishing number of the country which as granted/extended/refused/withdrawn approval (see approval provisions in the Regulations).
[2/] Strike out what does not apply.
       [3/] Indicate the appropriate marking selected from the list below:

[1/] Letters in brackets refer to headlamps intended for left-hand traffic.
[14/] See the corresponding footnote in the text of the Regulation.
[1/] When the driving beam is reciprocally incorporated with the passing beam, HV in the case of the driving beam shall be the same measuring point as in the case of the passing beam.
[2/] HL and HR: points on "hh" located at 1,125m to the left and to the right of point HV respectively.
[1/] When the tested headlamp is grouped and/or reciprocally incorporated with signalling lamps, the latter shall be lit for the duration of the test.  In the case of a direction indicator lamp, it shall be lit in flashing operation mode with an on/off time ratio of approximately one to one.
[2/] Should two or more lap filaments be simultaneously lit when headlamp flashing is used, this shall not be considered as being normal use of the filaments simultaneously.
