applies to motor vehicle headlamps which may incorporate lenses of glass or plastic material.

       1. DEFINITIONS

        For the purpose of this Regulation,

       1.1. "Lens" means the outermost component of the headlamp (unit) which transmits light through illuminating surface;

       1.2. "Coating" means any product or products applied in one or more layers to the outer face of a lens;

       1.3. "Headlamps of different types" are headlamps which differ in such essential respects as:

       1.3.1. the trade name or mark;

       1.3.2. the characteristics of the optical system;

       1.3.3. the inclusion or elimination of components capable of altering the optical effects by reflection, refraction, absorption and/or deformation during operation. However, the fitting or elimination of filters designed solely to change the colour of the beam and not its light distribution shall not constitute a change in the type;

       1.3.4. suitability for right-hand or left-hand traffic or for both traffic systems;

       1.3.5. the kind of beam produced (passing beam, driving beam or both;)

       1.3.6. the holder  intended  to  accommodate  the  filament  lamp  (or  lamps)  of one of  the categories H1, H2, H3, HB3, HB4, H7, H8, H9, HIR1 and/or HIR2;[2/][*/]

       1.3.7. the materials constituting the lenses and coating, if any.

       2. APPLICATION FOR APPROVAL OF A HEADLAMP [3/]

       2.1. The application for approval of a headlamp shall be submitted by the owner of the trade name or mark or by his duly accredited representative. It shall specify:

       2.1.1. whether the headlamp is intended to provide both a passing beam and driving beam or only one of these beams;

       2.1.2. whether, if the headlamp is intended to provide a passing beam, it is designed for both left-hand and right-hand traffic or for either left-hand or right-hand traffic only;

       2.1.2.1. if the headlamp is equipped with an adjustable reflector, the mounting position(s) of the headlamp in relation to the ground and the longitudinal median plane of the vehicle;

       2.1.3. the colour of the beam emitted by the headlamp.

       2.2. Every application shall be accompanied by:

       2.2.1. drawings  in  triplicate  in  sufficient  detail  to  permit  identification  of  the  type  and representing a frontal view of the headlamp, with details of lens ribbing if any, and the cross-section; the drawings shall indicate the space reserved for the approval mark;

       2.2.1.1. if the headlamp is equipped with an adjustable reflector, an indication of the mounting position(s) of the headlamp in relation to the ground and the longitudinal median plane of the vehicle, if the headlamp is for use in that (those) position(s) only;

       2.2.2. In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the competent authority responsible for approval tests. The manufacturer is responsible for proving that the applied
