Proposal from the Simplification of Lighting Regulations informal group to combine provisions of UN Regulations Nos. 4, 6, 7, 23, 38, 50, 77, 87 and 91 into a single regulation. This consolidation aims to streamline the administration and implementation of these lighting regulations while setting the foundation for a future shift towards performance-based approval requirements. This proposal restructures the existing body of lighting regulations without changing their content (e.g., technical requirements).
