or light generator it shall be checked, that:

5.8.1. The design of the LED module(s) or light generator(s) shall be such that they can be fitted in no position other than the correct one.
5.8.2. Non-identical light source modules, if any, shall be non-interchangeable within the same lamp housing.
5.8.3. The LED module(s) or light generator(s) shall be tamperproof.
5.9. In case of front fog lamps with light source(s) having a total objective luminous flux that exceeds 2,000 lumens, a reference shall be made in item 10.8. of the communication form in Annex 1.
5.10. If the lens of the front fog lamp is made of plastic material tests shall be done according to the requirements in Annex 6.
5.10.1. The UV resistance of light transmitting components located inside the front fog lamp and made of plastic material shall be tested according to Annex 6, paragraph 2.7.
5.10.2. The test in paragraph 5.11.1. above is not necessary if low-UV type light sources as specified in Regulation No. 99 or in Annex 12 to this Regulation are used, or if provisions are taken, to shield the relevant lamp components from UV radiation, e.g. by glass filters.
5.11. The front fog lamp and its ballast system or light source control gear shall not generate radiated or power line disturbances, which cause a malfunction of other electric/electronic systems of the vehicle.[6]
5.12. Front fog lamps, designed to operate permanently with an additional system to control the intensity of the light emitted, or which are reciprocally incorporated with another function, using a common light source, and designed to operate permanently with an additional system to control the intensity of the light emitted, are permitted.
5.13. In the case of Class F3 the sharpness and linearity of the cut-off shall be tested according to the requirements of Annex 9.

6.  Illumination
6.1. Front fog lamps shall be so designed as to provide illumination with limited dazzle.
6.2. The luminous intensity produced by the front fog lamp shall be measured at 25 m distance by means of a photoelectric cell having a useful area comprised within a square of 65 mm side.
The point HV is the centre-point of the coordinate system with a vertical polar axis. Line h is the horizontal through HV (see Annex 4 to this Regulation).
6.3. In the case of Class B front fog lamps:
6.3.1. A colourless standard (étalon) filament lamp as specified in Regulation No. 37, of the category specified by the manufacturer, which may be supplied by the manufacturer or applicant, shall be used.
6.3.1.1. During the testing of the front fog lamp the power supply for this filament lamp shall be regulated so as to obtain the
