Document Title Proposal for Supplement 16 to Regulation No. 91
Reference Number GRE/2015/14
Date
28 Jan 2015
Summary 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.

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.

31. GRE noted that this proposal would be considered at the next session in conjunction with a similar proposal for amendments to Regulation No. 7 (see para. 24 of this report).
