Proposal to amend UN R74 series 04 by simplifying the definition in paragraph 2 through deletion of common definitions to UN R48, applying amendments for failure provision and EV inclusion, aligning terminology and format with UN R48 and UN R53, retaining only the latest transitional provisions, simplifying paragraphs 6.×.4 and 6.×.5, and providing editable pictures.

Proposal to amend the definitions ; add EV inclusion; clarify individual and general provisions, failure provisions, and transitional provisions; correct signal lamp category; use category symbol instead of lamp function name;

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.

Baseline document for amending UN R74 (based on WP.29/2024/91, SLR-71-07, SLR-71-7, SLR-66-01, and SLR-73-07). Key changes include: simplifying definitions; using “type-approved” and “type-approval” with hyphens per UN R48; replacing “vehicle type (moped)” with “type of vehicles of category L₁”; adding hyphenation to “direction-indicator lamp”; deleting “above” from paragraph references; clarifying UN R48 series; removing “to this Regulation” after Annex references; applying scientific notation for lumens; including electric vehicles; revising individual and general provisions; correcting signal lamp category errors; and using category symbols instead of lamp function names.

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.

Proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86.

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.

Proposal prepared by the SLR informal group in cooperation with IMMA in order to delete definitions in UN R74.01 made redundant because they already exist in UN R48. The aim of this proposal is to confirm UN R48 as the sole repository for common definitions used across all lighting regulations.

Under UN R112, a Class B lighting device that fulfills the requirements for Class A headlamps may be approved. However, UN R74 prohibits the use of Class B devices in this manner. Therefore, this proposal would remove the discrepancy and enable the installation of Class B devices approved under UN R112 as headlamps.

Text prepared by Italy to delete all obsolete references in Regulations Nos. 53 and 74 in order to avoid confusion and possible incorrect application of the requirements containing these references. The deletions cover references to Regulations Nos. 1, 8, 20, 56, 57, 72, 76 and 82. These regulations have all been “frozen” (i.e., they do not apply to new type approvals) and their functions have been taken over by Regulations Nos. 112 and 113.

Proposal to enable the optional use of hazard warning lamps on L1 category vehicles to alert other vehicles in case of breakdown or other situations that could lead to danger on the road. This proposal brings L1 category warning signal options in line with those for other 2-wheeled vehicles.

IMMA correction (of an oversight on
inclusion of the colors of the lights from R53 to ensure complete alignment of UN R74 with R53) to its proposal to enable the optional use of hazard warning lamps on L1 category vehicles to alert other vehicles in case of breakdown or other situations that could lead to danger on the road.

Proposal to enable the optional use of hazard warning lamps on L1 category vehicles to alert other vehicles in case of breakdown or other situations that could lead to danger on the road.

This proposal brings L1 category warning signal options in line with those for other 2-wheeled vehicles.

Pursuant to item 5(f) of GRE-69, the GTB proposal (GRE/2013/5) to cease issuing type approvals under UN R5 and R31 was approved.

This prompted proposals to look for similar references in UN R53, R74 and R86. No references to UN R31 were found, but references to similarly ‘frozen’ regulations (UN R1, R8, R20, R56, R57, R72, R76 and R82) were found.

The present document proposes to delete these obsolete references in UN R53 and R74.
