5.2.3. There shall be no lateral variations detrimental to good visibility in zone III..
5.2.4. Headlamps designed to meet the requirements of both right-hand and left-hand traffic shall, in each of the two setting positions of the optical unit, light source(s) or light source module(s) producing the principal passing-beam, meet the requirements set forth above for the corresponding direction of traffic.
5.2.5. The requirements in paragraph 5.2.2. shall also apply to headlamps designed to provide bend lighting and/or that include the additional light source(s) or light source module(s) referred to in paragraph 5.2.6.
5.2.5.1. If bend lighting is obtained by:
5.2.5.1.1. Swivelling the passing-beam or moving horizontally the kink of the elbow of the cut-off, the measurements shall be carried out after the complete headlamp assembly has been re-aimed horizontally, e.g. by means of a goniometer;
5.2.5.1.2. Moving one or more optical parts of the headlamp without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with these parts being in their extreme operating position;
5.2.5.1.3. Means of additional light source(s) or light source module(s) without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with this/these light source(s) or light source module(s) activated.
5.2.6. Additional UN approved light sources and/or additional light source module(s) may be used inside the passing-beam headlamp to contribute to bend lighting;
5.2.7. Additional UN approved light sources and/or additional light source module(s), inside the passing-beam headlamp, may be used for the purposes of generating infrared radiation. It/they shall only be activated at the same time as the principal light source(s) or light source module(s). In the event that (one of) the principal light source(s) or (one of) the principal light source module(s) fails, this (these) additional light source(s) and/or light source module(s) shall be automatically switched OFF;
5.2.8. In the event of failure of one or more additional light source(s), or one or more additional light source module(s) as described in paragraphs 5.2.6. and 5.2.7., the headlamp shall continue to fulfil the requirements of the passing-beam.
5.3. Technical requirements concerning adaptive front-lighting systems (AFS) and concerning adaptive driving-beam (ADB) for vehicles of category L3 (symbols “XC”, “XCE”, “XCV”, “XCW”, “XR” and “ADB”)
