lamps, direction indicators, and rear-registration-plate illuminating devices intended to be fitted to mopeds, motor cycles and vehicles treated as such.

       2. DEFINITIONS

       For the purpose of this Regulation,

       2.1. "lamp" means a device designed to illuminate the road or to emit a luminous signal; rear- registration-plate illuminating devices and reflex reflectors shall likewise be regarded as lamps;

       2.1.1. "independent lamps" means lamps having separate lenses, separate light sources and separate lamp bodies;

       2.1.2. "grouped lamps" means devices having separate lenses and separate light sources, but a common lamp body;

       2.1.3. "combined" means devices having separate lenses but a common light source and a common lamp body;

       2.1.4. "reciprocally incorporated" means devices having separate lights sources (or a single light source operating in different ways), totally or partial common lenses and a common lamp body;

       2.2. "front position lamp" means the lamp used to indicate the presence of the vehicle when viewed from the front;

       2.3. "rear position lamp" means the lamp used to indicate the presence of the vehicle when viewed from the rear;

       2.4. "stop lamp" means the lamp used to indicate to other road users to the rear of the vehicle that the driver is applying the service brake;

       2.5. "direction indicator lamp" means the lamp used to indicate to other road users that the driver intends to change direction to the right or to the left: (see also Annex 1);

       2.5.1. "direction indicator lamp of the category 11" means a direction indicator lamp intended to be fitted to the front of the vehicle;

       2.5.2. "direction indicator lamp of the category 12" means a direction indicator lamp intended to be fitted to the rear of the vehicle;

       2.5.3. "direction indicator lamp of the category 31" means a direction indicator lamp intended to be fitted on the side of the vehicle, [1/]

       2.6. "rear-registration-plate illuminating device" means the device used to illuminate the space reserved for the rear registration plate; such device may consist of various optical components (see also Annex 6);

       2.7. "illuminating surface" (see Annex 7);

       2.7.1. "light-emitting surface" means all or part of the surface of the transparent material that encloses the lighting device and allows compliance with photometric and colorimetric characteristic standards;

       2.7.2. "illuminating surface of a light-signalling device" means the orthogonal projection of the lamp on a plane perpendicular to its axis of reference and in contact with the transparent outer surface of the lamp such projection being bounded by the covering of the screen edges situated in that plane and each allowing only 98% of the total intensity of the lamp to subsist in the direction of the axis of reference; for the purposes of determining the lower, upper and lateral edges of
