       The provisions laid down in paragraph 5.3.2 above are applicable.

       5.3.3.1. In addition, where the same lens is used, the latter may bear the different approval marks relating to the different types of headlamps or units of lamps, provided that the main  body of the headlamp, even if it cannot be separated from the lens, also comprises the space described, in paragraph 4.2 above and bears the approval mark of the actual functions.

       6. GENERAL SPECIFICATIONS

       6.1. Each sample shall conform to the specifications set forth in this paragraph 6 and in paragraphs 7 and 8 below, and, if necessary, paragraph 9.

       6.2. SB units shall be so made as to, retain their prescribed photometric characteristics and to remain in good working order when in normal use, despite the vibrations to which they may be subjected.

       6.2.1. Headlamps shall be fitted with a device enabling them to be so adjusted on the vehicle as to comply with the rules applicable to them.  Such a device need not be fitted on the SB headlamp inserts if the use of such inserts is confined to vehicles on which the headlamp setting can be adjusted by other means.  Where an SB headlamp providing a driving  beam  and  an  SB  headlamp  providing a passing  beam  are  assembled  as exchangeable subunits to form a composite unit the adjusting device shall enable each SB unit individually to be duly adjusted.

       6.2.2. However, this will not apply to headlamp assemblies whose reflectors are indivisible.  For this type of assembly the requirements of paragraph 8 of this Regulation shall apply.  In the case where more than one light source is used to provide the main beam the combined main-beam functions will be used to determine the maximum value of the illumination (E max).

       6.3. The terminals shall only be in electrical connection with the appropriate filament or filaments
