Annex 6 to this Regulation.

       7.11. The photometric performance lamps equipped with several light sources shall be checked in accordance with the provisions of Annex 4.

       8. TEST PROCEDURE

       8.1. All measurements shall be carried out with an uncoloured standard filament lamp of the category prescribed for the advice, adjusted to produce the reference luminous flux prescribed for the filament lamp involved (see Regulation No. 37).

       "All measurements on lamp with non-replaceable light sources shall be made at 6.75 V and 13.5 V respectively."

       8.2. The vertical and horizontal outlines of the illuminating surface of a light-signalling device (paragraph 2.7.2.) shall be determined and measured in relation to the centre of reference (paragraph 2.10).

       9. COLOUR OF LIGHT EMITTED

       Stop lamps and rear position lamps shall emit red light, front position lamps may emit white or selective-yellow light, direction indicators shall emit amber light.

       The colour of the light emitted, measured using a light source having a colour temperature of 2856 K, [5/] shall be within the limits of the co-ordinates prescribed for the colour in question in Annex 5 to this Regulation.

       However, for lamps equipped with non-replaceable light sources, the colorimetric characteristics should be verified with the light sources present in the lamps at a voltage of 6.75 V, 13.5 V or 28.0 V.

       10. CONFORMITY OF PRODUCTION

       Every device bearing an approval mark as prescribed under this Regulation shall conform to the type approved and shall comply with the requirements of this Regulation. However, in the case of a device picked at random from series production, the requirements as to the respectively minimum and maximum intensities of the light emitted (measured with a standard filament lamp as referred to in paragraph 8 above) shall be at least 80% of the minimum values specified and not exceed 120% of the maximum values allowed.

       11. PENALTIES FOR NON-CONFORMITY OF PRODUCTION

       11.1 The approval granted in respect of a device pursuant to this Regulation may be withdrawn if the foregoing conditions are not observed.

       11.2 If a Contracting Party to the Agreement, applying this Regulation, withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a copy of the approval form bearing at the end, in large letters, the signed and dated annotation "APPROVAL WITHDRAWN".

       12. PRODUCTION DEFINITELY DISCONTINUED

       If the holder of the approval completely ceases to manufacture a device approved in accordance with this Regulation, he shall so inform the authority which granted the approval.  Upon receiving the relevant communication, that authority shall inform thereof the other Parties to the Agreement which apply this Regulation by means of a copy of the approval form bearing at
