The Working Party on Lighting and Light-Signalling (GRE) is the subsidiary body of the World Forum for Harmonization of Vehicle Regulations (WP.29) that prepares regulatory proposals on active safety, specifically regarding vehicle Lighting and Light-Signalling to WP.29. This group of experts conducts research and analysis to develop lighting requirements for vehicles.
GRE convenes officially twice a year and entrusts informal groups with specific problems that need to be solved urgently or that require special expertise. More than 70 experts participate at the sessions of GRE.
The Working Party is open to the governmental experts from any member country of the United Nations, and to any regional economic integration organization set up by member countries of the United Nations, and to experts of governmental organizations. Experts of non-governmental organizations (NGOs) may participate in a consultative capacity. Final decisions are taken by Government representatives by vote at the World Forum WP.29 level.
