produce the reference luminous flux prescribed for that category of lamp.

       7.1.1. All measurements on lamps equipped with non-replaceable light sources (filament lamps and other) shall be made at 6.75 V, 13.5 V or 28.0 V respectively.

       In the case of light sources supplied by a special power supply, the above test voltages shall be applied to the input terminals of that power supply.  The test laboratory may require from the manufacturer the special power supply needed to supply the light sources.

       7.2. However, in the case of an indicator of category 2b for which an additional system[4/] is used to obtain the night-time intensity, the voltage applied to the system for measuring the night-time intensity shall be that which was applied to the filament lamp for measuring the day-time intensity.

       7.3. The vertical and horizontal outlines of the illuminating surface of a light-signalling device (paragraph 1.2.2.) shall be determined and measured in relation to the centre of reference (paragraph 1.2.5.).

       8. COLOUR OF LIGHT EMITTED

       The colour of the light emitted shall be within the limits of the co-ordinates prescribed in Annex 5 to this Regulation.

       9. MODIFICATIONS OF A TYPE OF DIRECTION INDICATOR FOR MOTOR VEHICLES AND THEIR TRAILERS AND EXTENSION OF APPROVAL

       9.1. Every modification of a type of direction indicator shall be notified to the administrative department which approved the type. The department may then either:

       9.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the device still complies with the requirements; or

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

       9.2. Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 4.1.4. above to the Parties to the Agreement applying this Regulation.

       9.3. The competent authority issuing the extension of approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 2 to this Regulation.

       10. CONFORMITY OF PRODUCTION

        The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev. 2), with the following requirements:

       10.1. Direction indicators approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraphs 6 and 8 above.

       10.2. The minimum requirements for conformity of production control procedures set forth in Annex 6 to this Regulation shall be complied with.

       10.3. The minimum requirements for sampling by an inspector set forth in Annex 7 to this Regulation shall be complied with.

       10.4. The authority
