6.2.1.1.3.1 In the light-distribution as specified in Table 19, single narrow spots or stripes inside the area including the measuring points   1 to   10 and line   1 or inside the area of line   1 and line   2 with not more than   2.10∙10 2   cd are allowed, if not extending beyond a conical angle of   2° aperture or a width of   1°. If multiple spots or stripes are present, they shall be separated by a minimum angle of   10°.

 

6.2.1.1.3. 1. 2. If the results of the test described above do not meet the requirements, the alignment of the front fog lamp may be changed according to the provisions in Annex 5, paragraph. 4.1.
