Since 1952 the GTB has been recognised as the global group of vehicle manufacturers, system suppliers, light source manufacturers, testing laboratories and academia working to assure regulation and safety of automotive lighting systems and their installation.

GTB membership includes 17 delegations from countries, including Europe, USA and Japan. Representation in national delegations comes from industry, approval testing laboratories, regulatory agencies and academia. 

Our principal activity today is the preparation of proposals for new and amended UNECE Regulations, taking into account technical development, actual testing experience and the safety and economic implications with a view to practical application.
