geometric visibility definition

geometric visibility means the angles which determine the square field in which the light- emitting surface of the lighting device is completely visible when the relevant angles (α vertical and β horizontal) are measured at the outward contour of the apparent surface and the lamp is observed from afar, however, if any obstacles is located within this field and partly obscuring the light-emitting surface, it may be accepted where it is proven that, even with such obstructions, the photometric values prescribed for the type-approval of the lighting device as component are complied with;
geometric visibility. Horizontal angle: For the two rear position lamps: either 45° inwards and 80° outwards, or 80° inwards and 45° outwards. The horizontal inward angle may be reduced to 30° if the shape of the bodywork makes it impossible to reach 45°. Vertical angle: 15° above and below the horizontal. The angle below the horizontal may be reduced to 10° if the height of the lamp above the ground is less than 1,900 mm, and to 5° if this height is less than 750 mm.
geometric visibility. Horizontal angle: For the two front position (side) lamps: 10° inwards and 80° outwards. However, the angle of 10° inwards may be reduced to 5° if the shape of the bodywork makes it impossible to keep to 10°. For tractors with any overall width not exceeding 1,400 mm this angle may be reduced to 3° if the shape of the bodywork makes it impossible to keep to 10°. Vertical angle: 15° above and below the horizontal. The vertical angle below the horizontal may be reduced to 10° if the height of the lamp above the ground is less than 1,900 mm, and to 5° if this height is less than 750 mm.
