Paragraph 6.4.1.4., amend to read:

“6.4.1.4. In the case of LED modules:

• All measurements on front fog lamps equipped with LED module(s) shall be made at 6.3 V, 13.2 V or 28.0 V respectively, if not otherwise specified within this Regulation. LED modules operated by an electronic light source control gear shall be measured with the input voltage as specified by the applicant. or with a supply and operating device which replace this control gear for the photometric test. The relevant input parameters (e.g. duty cycle, frequency, pulse shape, peak voltage) shall be specified and stated in the communication form, item 10.6., in Annex 1 to this Regulation.
  
  
• The measured luminous intensity values shall be multiplied by a factor 0.7 prior to the check for compliance."

Annex 5, paragraph 1.1.2.5., renumber as paragraph 1.1.2.(g).
