Japanese perspectives on selected regulations (NU R4, 34, 46, and 79) within the context of adoption of the International Whole Vehicle Type Approval system/regulation.

Proposed modifications to the German proposal (GRE/2012/20) to ensure that non-replaceable and unapproved filament light sources used in sealed devices and in (filament) light-source modules have a sufficient lifetime and fulfill color endurance verification.

Proposal from Germany to insert provisions for the use of incandescent light sources in the case of light source modules and lamps with non-replaceable light sources.

Proposal as adopted by the Working Party on Lighting and Light-Signalling (GRE) at its sixty-seventh session to introduce provisions for replaceable light-emitting diode (LED) light sources and to correct and harmonize the provisions concerning approval markings.

The Forum adopted a new UN Regulation on LED light sources at its March 2012 session. This document updates the collective amendment that introduces LED light sources into the relevant UN Regulations 4, 6, 7, 23, 38, 50, 77, 87, 91 and 119.

This proposal mainly corrects an unintended, but potentially costly, obligatory (rather than optional) use of mingled letters in the marking provisions of UN R23. The proposal also corrects the marking provisions of UN R4 and R23 by deleting an unnecessary hyphen.
