4. Simplification of lighting and light-signalling UN Regulations

8. The expert from the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) reported on their progress and requested guidance from GRE (GRE-81-19). The expert from Poland commented on the IWG SLR request (GRE-81-22). GRE agreed that:

  • The headlamp provisions should continue to be expressed in terms of the luminous intensities equivalent to the illuminance measured on a screen at a distance of 25 m.
  • All technologies should be allowed for all SLR functions. Requirements should be common for all technologies; test requirements could be technology-specific.
  • Combination of different light source technologies should be possible for all SLR functions.
