24. The expert of GTB introduced ECE/TRANS/WP.29/GRE/2015/8 with a proposal to update the provisions relating to failure of light sources when an operating tell-tale is installed. GRE noted that this document was part of collective amendments to various Regulations (ECE/TRANS/WP.29/GRE/2015/10, ECE/TRANS/WP.29/GRE/2015/11, ECE/TRANS/WP.29/GRE/2015/12, ECE/TRANS/WP.29/GRE/2015/14, ECE/TRANS/ WP.29/GRE/2015/18). Following comments from the experts of Germany and the Netherlands, GRE requested GTB to revise the proposal and submit a new document to the next session. |
GRE/2015/8 | Proposal for Supplement 25 to the 02 series of amendments to Regulation No. 7
Proposal for Supplement 25 to the 02 series of amendments to Regulation No. 7
This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.
GRE/2015/10 | Proposal for Supplement 21 to Regulation No. 23
Proposal for Supplement 21 to Regulation No. 23
This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.
GRE/2015/11 | Proposal for Supplement 18 to Regulation No. 38
Proposal for Supplement 18 to Regulation No. 38
This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale. In paragraph 9, the opportunity has been taken to correct a reference to paragraph 3. of Annex 4. The reference should be to paragraph 4 of Annex 4.
GRE/2015/12 | Proposal for Supplement 17 to Regulation No. 77
Proposal for Supplement 17 to Regulation No. 77

GRE/2015/14 | Proposal for Supplement 16 to Regulation No. 91
Proposal for Supplement 16 to Regulation No. 91
This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.
