by the angle quoted in paragraph 2.1.4. or 2 degrees, whichever is smaller, by means of the headlamp aiming devices.  The headlamp is then re-aimed downwards (by means of the goniometer), and the photometric specifications must be met at the following points: Passing beam: HV and 75 R (75 L respectively)

       Driving beam: E max, HV as percent of Emax

       If the aiming devices do not allow a continuous movement, the position nearest to 2 degrees is chosen.

       6.5.3. The reflector is brought back to its nominal angular position as defined in paragraph 6.2.2., and the goniometer is set back to its position of origin.  The reflector is tilted vertically downwards by the angle quoted in paragraph 2.1.4., or 2 degrees, whichever is smaller, by means of the headlamp aiming device.  The headlamp is then re-aimed upwards (by means of the goniometer for example) and points as in paragraph 6.5.2. are checked.

       7. GAUGING OF DISCOMFORT

       The discomfort caused by the passing beam of headlamps shall be gauged. [11/]

       C. FURTHER ADMINISTRATIVE PROVISIONS

       8. MODIFICATION   OF   THE   HEADLAMP   TYPE   AND   EXTENSION   OF APPROVAL

       8.1. Every modification of the headlamp type including the ballast shall be notified to the administrative department which approved the headlamp type.  The said department may then either:

       8.1.1. Consider that the modifications made are unlikely to have appreciable adverse effects and that in any event the headlamp still complies with the requirements; or

       8.1.2. Require a further test report from the technical service responsible for conducting the tests.

       8.2. Confirmation or refusal or approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 4.1.5. above to the Contracting Parties to the Agreement which apply this Regulation.

       8.3.

       9. CONFORMITY OF PRODUCTION

       9.1. Headlamps approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraph 6.

       9.2. In order to verify that the requirements of paragraph 9.1. are met, suitable controls of the production shall be carried out.

       9.3. The holder of the approval shall in particular:

       9.3.1. ensure the existence of procedures for the effective control of the quality of products:

       9.3.2. have access to the control equipment necessary for checking the conformity to each approved type;

       9.3.3. ensure that data of test results are recorded and that related documents shall remain available for a period to be
