accepted by the Type Approval Authority, as provided by the applicant.
6.1.9.3.3.2.              A test-drive according to paragraph 1 in Annex 12. The performance of the automatic control shall be documented and checked against the applicant's description. Any obvious malfunctioning shall be contested (e. g. excessive angular movement or flicker).
6.1.9.3.4.              The control of the main-beam headlamps may be such that the main-beam headlamps are switched ON automatically only when:
              (a) No vehicles, as mentioned in paragraph 6.1.7.1. above, are detected within the fields and distances according to paragraphs 6.1.9.3.1.1. and 6.1.9.3.1.2.; and
              (b) The detected ambient lighting levels are as prescribed in paragraph 6.1.9.3.5. below.
6.1.9.3.5.              In the case where main-beam headlamps are switched ON automatically, they shall be switched OFF automatically when oncoming or preceding vehicles, as mentioned in paragraph 6.1.7.1. above, are detected within the fields and distances according to paragraphs 6.1.9.3.1.1. and 6.1.9.3.1.2.
Moreover, they shall be switched OFF automatically when the illuminance produced by ambient lighting conditions exceeds 7000 lx.
Compliance with this requirement shall be demonstrated by the applicant, using simulation or other means of verification accepted by the Type Approval Authority. If necessary, the illuminance shall be measured on a horizontal surface, with a cosine corrected sensor on the same height as the mounting position of the sensor on the vehicle. This may be demonstrated by the manufacturer by sufficient documentation or by other means accepted by the Type Approval Authority.
6.2.                                    Dipped beam headlamp (Regulations Nos. 98 and 112)
6.2.1.                              Presence
Mandatory on motor vehicles. Prohibited on trailers.
6.2.2.                              Number
Two, type approved according to Regulations Nos. 98 or 112, excluding Class A headlamp.
6.2.3.                              Arrangement
No special requirement.
6.2.4.                              Position
6.2.4.1.                        In width: that edge of the apparent surface in the direction of the reference axis which is farthest from the vehicle's median longitudinal plane shall be not more than 400 mm from the extreme outer edge of the vehicle.
The inner edges of the apparent surfaces in the direction of the reference axes shall be not less than 600 mm apart. This does not apply, however, for M1 and N1 category vehicles; for all other categories of motor vehicles this distance may be reduced to 400 mm where the overall width of the vehicle is less than 1,300 mm.
6.2.4.2.                        In height: not less than 500 mm and not more than 1,200 mm above the ground. For category N3G (off-road) vehicles[11] the maximum height may be increased to 1,500 mm.
6.2.4.3.                        In length: at the front of the vehicle. This requirement shall be deemed to be satisfied if the light emitted does not cause discomfort to the driver either directly or indirectly through the devices for indirect vision and/or other reflecting
