be not less than the minima specified in that annex.  However, in the case where the reversing lamp is intended to be installed on a vehicle exclusively in a pair of devices, the photometric intensity may be verified only up to an angle of 30 degrees inwards where a photometric value of at least 25 cd shall be satisfied.
This condition shall be clearly explained in the application for approval and relating documents (see paragraph 2 of this Regulation).
Moreover, in the case where the type approval will be granted applying the condition above, a statement in paragraph 11 "Comments" of the communication form (see annex 1 to this Regulation), will inform that the device shall only be installed in a pair.
6.5. In the case of a single lamp containing more than one light source, the lamp shall comply with the minimum intensity required when any one light source has failed and when all light sources are illuminated the maximum intensities shall not be exceeded.
7. TEST PROCEDURE
7.1. All measurements shall be carried out with uncoloured standard filament lamps of the types prescribed for the device, adjusted to produce the normal luminous flux prescribed for those types of filament lamps.
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.

8. COLOUR OF LIGHT EMITTED
The colour of the light emitted shall be white.  In case of doubt, the colour may be checked on the basis of the definition of the colour of white light given in annex 4 to this Regulation.
9. 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:
9.1. Lamps 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.
9.2. The minimum requirements for conformity of production control procedures set forth in
annex 5 to this Regulation shall be complied with.
9.3. The minimum requirements for sampling by an inspector set forth in annex 6 to this regulation shall be complied with.
9.4. The authority which has granted type approval may at any time verify the conformity control methods applied in each production facility.  The normal frequency of these verifications shall be once every two years.
