Subsequent numbers will be assigned to other countries in the chronological  order in which they ratify or accede to the Agreement Concerning the Adoption of Uniform Technical Prescriptions for Wheeled Vehicles, Equipment and Parts which can be Fitted and/or be Used on wheeled Vehicles and the Conditions for Reciprocal Recognition of Approvals Granted on the Basis of these Prescriptions, and the numbers thus assigned shall be communicated by the Secretary-General of the United Nations to the Contracting Parties to the Agreement.
[4/] Requirements for HSB units with a rated voltage of 24 volts are under consideration.
[5/] All photometric measurements shall be made at the rated voltage specified in paragraph 7.1.
[6/] If, in the case of an HSB unit designed to meet the requirements of this Regulation in respect of the passing beam only, the focal axis diverges appreciably from the general direction of the beam, lateral adjustment shall be effected in the manner which best satisfies the requirements for illumination at points 75 R and 50 R for right-hand traffic and 75 L and 50 L for left-hand traffic.
[7/] The test screen shall be wide enough to allow examination of the "cut-off" over a range of at least 5 degrees on either side of the line vv.
[8/] If the beam does not have a "cut-off" with a clear "elbow", lateral adjustment shall be effected in the manner which best satisfies the requirements for illumination at points 75 R and 50 R for right-hand traffic and 75 L and 50 L for left-hand traffic.
[9/] An HSB unit designed to emit a passing beam may incorporate a driving beam not subject to this specification.
[10/] The limit of realignment of 1 degrees to the right or left is not incompatible with vertical realignment upward or downward.  The latter is limited only by the requirements of paragraph 8.3. However, the horizontal part of the "cut-off" should not extend beyond the line hh (the provisions of paragraph 8.3. are not applicable to HSB units intended to meet the requirements of this Regulation only for provision of a passing beam).
[11/] Notwithstanding the provisions of article 3 of the 1958 Agreement concerning the Adoption of Uniform Conditions of Approval and Reciprocal Recognition of Approval for Motor Vehicle Equipment and Parts, the approval of an HSB unit under
