Provision Reference: 
Character Range: 176898–179810

farthest from the median longitudinal plane shall not be more than 150 mm from the extreme outer edge of the vehicle.
The distance between the inner edges of the two apparent surfaces in the direction of the reference axes shall:
For M1 and N1 category vehicles: No special requirement;
For all other categories of vehicles: Not less than 600 mm. This distance may be reduced to 400 mm where the overall width of the vehicle is less than 1,300 mm.
6.9.4.2.                        In height: above the ground, not less than 250 mm nor more than 1,500 mm (2,100 mm for O1 and O2 categories of vehicles, or if for any other categories of vehicles the shape of the bodywork makes it impossible to keep within 1,500 mm).
6.9.4.3.                        In length: no individual specification.
6.9.4.4.                        Where the front position lamp and another lamp are reciprocally incorporated, the apparent surface in the direction of the reference axis of the other lamp shall be used to verify compliance with the positioning requirements (paragraphs 6.9.4.1. to 6.9.4.3.).
6.9.5.                              Geometric visibility
6.9.5.1.                        Horizontal angle: 45° inwards and 80° outwards.
However, where a lamp is mounted below 750 mm (measured according to the provisions of paragraph 5.8.1. above), the inward angle of 45° may be reduced to 20° under the H plane.
In the case of trailers, the angle inwards may be reduced to 5°.
Vertical angle: 15° above and below the horizontal. However, where a lamp is mounted below 750 mm (measured according to the provisions of paragraph 5.8.1. above), the downward angle of 15° may be reduced to 5°.
6.9.5.2.                        For M1 and N1 category vehicles, as an alternative to paragraph 6.9.5.1. above, at the discretion of the manufacturer or his duly accredited representative, and only if a front side-marker lamp is installed on the vehicle:
Horizontal angle: 45° outwards to 45° inwards.
However, where a lamp is mounted below 750 mm (measured according to the provisions of paragraph 5.8.1. above), the inward angle of 45° may be reduced to 20° under the H plane.
Vertical angle: 15° above and below the horizontal.
However, where a lamp is mounted below 750 mm (measured according to the provisions of paragraph 5.8.1. above), the downward angle of 15° may be reduced to 5°.
To be considered visible, the lamp shall provide an unobstructed view of the apparent surface of at least 12.5 cm2. The illuminating surface area of any retro-reflector that does not transmit light shall be excluded.
6.9.6.                              Orientation
Forwards.
6.9.7.                              Electrical connections
In accordance with paragraph 5.11.
However, if a front position lamp is reciprocally incorporated with a direction-indicator the electrical connection of the front position lamp on the relevant side of the vehicle or
