the orthogonal projection, in a transverse vertical plane, of the effective surface from which the light is emitted. For a reflex-reflector, the effective surface is the visible surface of the reflex-reflecting optical unit.

- 1b. kategooria laternad <= 20 mm;- 3. ja 4. kategooria laternad - ei limiteerita.
The outer edges of the illuminating surfaces of the driving lamps shall in no case be closer to the extreme outer edge of the vehicle than the outer edges of the illuminating surfaces of the passing lamps. ... If front fog lamps are fitted on a motor vehicle they shall emit white or selective-yellow light, be two or, in the case of motor cycle, one in number and be placed in such a way that no point on their illuminating surface is above the highest point on the illuminating surface of the passing lamps. ... A single illuminating surface in the shape of a band shall be deemed to be two or an even number of lamps if it is placed symmetrically to the median longitudinal plane of the vehicle. The illumination of such a surface shall be provided by at least two light sources placed as close as possible to its ends.
