are not permitted.
6.3.6. In the light-distribution as specified in the table in paragraph 6.3.5. above, single narrow spots or stripes inside the area above 15° with not more than 230 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°.
6.4. In the case of Class F3 front fog lamps:
6.4.1. Depending on the light source, the following conditions shall apply.
6.4.1.1. In the case of replaceable filament light sources:
6.4.1.1.1. The front fog lamp shall comply with the requirements of paragraph 6.4.3. of this Regulation with at least one complete set of appropriate standard (étalon) lamps, which may be supplied by the manufacturer or applicant.
In the case of filament lamps operating directly under vehicle voltage system conditions:
The front fog lamp shall be checked by means of colourless standard (etalon) filament lamps as specified in Regulation No. 37.
During the testing of the front fog lamp, the power supply to the filament lamp(s) shall be regulated so as to obtain the reference luminous flux at 13.2 V as indicated on the relevant data sheet of Regulation No. 37.
6.4.1.1.2. In the case of a system that uses a light source control gear being part of the lamp, the voltage declared by the applicant shall be applied to the input terminals of that lamp.
6.4.1.1.3. In the case of a system that uses a light source control gear not being part of the lamp the voltage declared by the applicant shall be applied to the input terminals of that light source control gear. The test laboratory shall require from the applicant the special light source control gear needed to supply the light source and the applicable functions. The identification of that light source control gear if applicable and/or the voltage applied including the tolerances shall be noted in the communication form in Annex 1 to this Regulation.
         6.4.1.2. In the case of a gas-discharge light source:
         A standard light source shall be used as specified in Regulation No. 99, which has been aged during at least 15 cycles, in accordance with paragraph 4. of Annex 4 to Regulation No. 99.
         During testing of the front fog lamp the voltage at the terminals of the ballast or at the terminals of the light source in case the ballast is integrated with the light source shall be regulated to maintain 13.2 V for a 12 V system, or at the vehicle voltage as specified by the applicant, with a tolerance of ±0.1 V.
         The objective luminous flux of the gas-discharge light source may differ from
