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. This proposal supersedes and replaces document GRE/2014/22 and has been prepared to remove ambiguities identified in the previous proposal.
13. The expert from GTB proposed to remove a conflict with the text of Regulation No. 19 on markings of front fog lamps that are reciprocally incorporated with the main beam (ECE/TRANS/WP.29/GRE/2014/22, GRE-72-10). GRE adopted this proposal as contained in Annex VII to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as a draft Supplements not only to the 06, but also to the 04 and 05 series of amendments to Regulation No. 48.
