Front fog lamps may be reciprocally incorporated with the main beam and in some cases, it is required to switch off the front fog lamp when the main beam is operated to avoid overheating of the device. In this case, Regulation No. 19 requires a “/” in the approval marking. However, the current text in paragraph 6.3.7 of Regulation No. 48 requires that “it shall be possible to switch the front fog lamps ON and OFF independently of the main-beam headlamps”. This proposal is intended to remove the conflict between the texts of the two regulations.
