Proposal to improve the applicability of paragraph 5.7.1.3.1. (concerning the separation of grouped direction indicator and stop lamps in order to avoid “signal mix”). To improve the present requirements of paragraph 5.7.1.3.1.on the basis of the colour changes concept, three alternative approaches for a suitable separation of direction indicator lamps and stop lamp are proposed:
a) the improved test of the existing paragraph 5.7.1.3.1. clarifies its application to lamps composed of more than one part and deletes the concept of “adjacent” parts of the lamps (that in the past led to different interpretations) in favour of a description of the condition of application of the requirement;
b) the unchanged text of the following paragraph 5.7.1.3.2.;
c) a new paragraph 5.7.1.3.3. to provide for specific electrical connections of the involved functions, in conjunction with the requirements of paragraph 5.9.2.
14. The expert from GTB proposed to clarify the application of paragraph 5.7.1.3. on separating the rear direction indicator lamps and stop lamps (ECE/TRANS/WP.29/GRE/2015/3 and GRE-73-15). The experts of France, Germany, Japan and UK did not support this proposal and pointed out that it was not sufficiently clear and allowed different interpretations. GRE invited GTB to revise the proposal based on the comments received.
