19. The expert from IEC proposed amendments to Regulations Nos. 37, 99 and 128 that aligned the approval code for light sources with the approval number as prescribed by Revision 3 of the 1958 Agreement (ECE/TRANS/WP.29/GRE/2018/21 and GRE-78-18). GRE adopted the amendments and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their November 2018 sessions.
20. On behalf of the Task Force on LED retrofits and substitutes (TF SR), the expert from Germany presented their status report (GRE-79-16). GRE supported the proposed two-step approach and mechanical interlock as a solution to avoid misuse of light emitting diode (LED) substitutes.
21. GRE recalled the earlier proposals by GTB to introduce LED substitutes and replaceable light sources into the new LSD and RID Regulations (ECE/TRANS/WP.29/GRE/2017/14, ECE/TRANS/WP.29/GRE/2017/15 and GRE-78-04) and noted that ECE/TRANS/WP.29/GRE/2017/15 had been incorporated in ECE/TRANS/WP.29/GRE/2018/3. GRE invited TF SR to update ECE/TRANS/WP.29/GRE/2017/14 and GRE-78-04.
22. The expert from GTB pointed out that the GTB guidelines for introducing and evaluating LED light source categories that were intended for forward lighting applications (GRE-77-04) should be published as a reference document on the GRE website. GRE agreed to this request.
