       5.3. 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 components in which the reflector and the diffusing lens cannot be separated provided the use of such units is confined to vehicles on which the headlamps setting can be adjusted by other means.  Where a headlamp providing a driving beam and a headlamp providing a passing beam, each equipped with its own filament lamp, are assembled to form a composite unit, the adjusting device shall enable each optical system individually to be duly adjusted.

       However, this shall not apply to headlamps assemblies whose reflectors are indivisible. For this type of assembly, the requirements of Paragraph 6 shall apply.

       5.4. The components by which the filament lamp is fixed to the reflector shall be so made that, even in darkness, the filament lamp can
