Document identifies challenges with headlamp aiming for glare prevention. UP-DOWN aiming challenges include vehicle actual load and cut-off line definition. LEFT-RIGHT aiming challenges include references on the vehicle and kink point definition. Cut-off line definition makes it difficult to check up-down aiming; kink point definition makes it difficult to check left-right aiming. The beam pattern must be used to check alignment. The way forward includes reviewing criteria for passing-beam orientation in approval and adapting inspection criteria accordingly.

This Regulation provides uniform provisions for approval of vehicles of categories M₁–M₃ and N₁–N₃ equipped with electric traction chain powertrain retrofit systems to be converted into pure electric vehicles (EV) or Hydrogen Fuel Cell Vehicles (HFCV). Retrofit system manufacturers must submit applications including descriptions of the retrofit system, original parent vehicle, modifications, compliance verification, application range, installed samples, authorized installers, and conversion plates. Type approval requires meeting general requirements for design, construction, durability, and failure communication, plus specific requirements in Annexes 5A for EVs and 5B for HFCVs. Only authorized installers may perform conversions, and manufacturers must provide installation documents and end-user manuals.

Identifies challenges with headlamp aiming across approval and inspection processes. Issues include determining vehicle actual load and cut-off line definition for up-down aiming, defining vehicle references and kink point location for left-right aiming, and separating aiming control from beam pattern assessment. Inspection data show rejection rates of 4.8 per cent for light duty vehicles and 2.8 per cent for heavy duty vehicles in France, with front fog lamp misalignment at 46 per cent. The document recommends reviewing approval criteria for passing-beam orientation and defining inspection procedures, equipment, and multibeam headlamp considerations.
