       2. DEFINITIONS

       For the purpose of this Regulation,

       2.1. "Sealed beam" headlamp unit (hereinafter termed "SB unit"), means a headlamp unit whose components, comprising a reflector system, a lens system and one or more electrical light sources are all parts of an integral whole which has been sealed in the course of manufacture and which cannot be dismantled without rendering the unit completely unusable;

       2.2. "Lens" means the outermost component of the headlamp (unit) which transmits 4light through the illuminating surface;

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

       2.4. SB units are considered to be of different types if they differ in one or more of the following essentials of form or characteristics:

       2.4.1. Trade name or mark;

       2.4.2. Characteristics of the optical system;

       2.4.3. Inclusion of additional components capable of altering the optical effects by reflection, refraction, absorption and/or deformation during operation;

       2.4.4. The rated voltage (the same approval number may be granted if the only change is of rated voltage);

       2.4.5.
