UN R53: Updated 05 series of amendments baseline document (IMMA)
|
SLR-78-09
|
2026-06-08 |
This document proposes draft provisions for a 05 series, updating the previous baseline (SLR-71-07). Key changes include simplification of definitions by referencing UN R48 where applicable; consolidation of geometric visibility requirements with uniform formatting; incorporation of electric vehicle (EV) provisions; inclusion of rear-end collision alert signal (RECAS); replacement of legacy terminology with hyphenated forms (e.g., "direction-indicator lamp," "type-approved"); use of scientific notation for luminous intensity values; and reduction of transitional provisions to retain only the 05 series requirements. Annex 3 has been reserved and deleted. The regulation applies to the installation of lighting and light-signalling devices on motorcycles and prescribes mandatory and optional devices with specifications for position, geometric visibility, orientation, electrical connections, and tell-tales. Transitional provision dates remain undecided. IMMA |
