2 Jun Horizontal adjustment of passing-beam/driving-beam and for AFS/ADB (OICA) TFGP-08-04 2026-06-02 OICA opposes introducing a regulatory requirement for horizontal adjustment of passing-beam/driving-beam and for AFS/ADB to the current SLR agenda. The proposal does not contribute to simplification of lighting regulations, no identified safety concern or ambiguity justifies this requirement, and it lacks a formal proposal from a Contracting Party, NGO, or other stakeholder. The SLR group is managing several longstanding unresolved issues, and introducing this topic risks further delaying progress. Harmonized requirements require comprehensive understanding of Periodic Technical Inspection specifications across all Contracting Parties, which are currently unavailable. OICA
