previous regulation next regulation
WP.29 Discussion Topic
Originally focused on the development of a new "horizontal reference document" as a repository of regulatory provisions common across lighting regulations, this program has evolved into a restructuring based upon light sources, lighting devices, and installation requirements. In particular, the Informal Working Group on the Simplification of Lighting Regulations is working towards the consolidation of lighting device regulations into three new regulations covering forward lighting, light signaling, and retro-reflecting devices.
