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.
