UN R86 baseline amendments add agricultural non-road mobile machinery to scope. Definitions are simplified by removing common vehicle definitions and aligning structure with UN R48. Headlamps symmetrical classes are reviewed following CLEPA comment. Side retro-reflector requirements align with EU requirements on location. Direction-indicator lamps alignment with EU scope for tractors remains an open point.

Proposal applies to vehicles of categories T, R, and S and agricultural NRMM regarding lighting and light-signalling device installation. The regulation establishes approval procedures, general specifications for lamp fitting and adjustment, electrical connections, and individual specifications for various lighting functions including driving-beam and passing-beam headlamps, direction-indicator lamps, stop lamps, position lamps, retro-reflectors, and other light-signalling devices. It specifies position requirements (height, width, length), geometric visibility angles, colour requirements, and electrical interconnection rules. Transitional provisions address implementation across different amendment series, with staggered acceptance periods for type-approvals granted under preceding series of amendments.

The agenda includes corrections to UN R150-01, baseline documents for UN R53, R74, R86, and R48, simplification of paragraphs 6.×.4 and 6.×.5, transitional provisions, harmonisation of requirements, apparent surface considerations, and direction indicator visibility improvements. The next meetings are scheduled for June and December 2026, with a potential September 2026 session in Tokyo.

SLR-76 session documents are available on the SLR website. Actions include: correcting errors in UN R150 for submission to GRE-94; preparing Stage 2/Step 2 baseline documents for UN R48, R53, R74, and R86; finalizing simplification of paragraphs 6.×.4 and 6.×.5; discussing apparent surface methodology; approving technological neutrality amendments to UN R48 and R149; collecting literature on rear direction indicator visibility; and reviewing harmonization requirements. SLR-77 meeting scheduled April 15-17, 2026 in Brussels.

Because the new lighting device regulations (LSD, RRD, and RID) each cover multiple lighting functions (e.g. direction indicators, marker lamps, DRL in the LSD regulation), the potential exists for a change in stringency to impact some, but not all functions within the scope of each regulation. The change index is proposed in order to track the impact on each function and so restrict the need for new type approvals only to those functions impacted by a change in stringency.
