56. The representative of the International Electrotechnical Commission (IEC) presented, on behalf of GTB, WP.29-156-08 dealing with replacement light sources and LED retrofit light sources for vehicles not in conformity with the provisions of UN Regulations. The representative of the Russian Federation underlined the high value of the presentation and the risks of low-quality after market products including for the new LED light sources. He added that the development of technical provisions for lighting devices was an ongoing activity of the IEC, including procedures for the conformity assessment. He suggested sending the presentation to IEC for further consideration at its Conformity Assessment Board. The cooperation and support of IEC on this matter would help in finding an acceptable market solution to prevent hazardous lighting devices. WP.29 acknowledged the importance of this issue to ensure vehicles and road safety and agreed to consider, at a future session, possible actions linked to the type approval procedure or periodical technical inspections ensuring the conformity of after market light sources.
