Proposal from the SLR informal group to align UN R48 with the 01series of amendments to UN R149 (road illumination devices). Para. 6.2.8.2. concerns the requirement for failure tell-tale of passing-beam headlamps (presence and activation) which only covers LED modules. The amendment proposes technology-neutral language. The proposal aims to complete the requirements to enable mandatory installation of headlamps approved to UN R149.01 per the request of the European Commission.
