Proposal to add component and separate technical unit approvals regulatory supplement to UN Regulation No. 158. The changes do not affect stringency and keep current type approvals valid. The proposal replaces the complete regulation text and includes definitions, requirements for close-proximity rear-view mirrors, rear-view camera systems, and detection systems for vehicles of categories M₁–M₃ and N₁–N₃. Field of vision requirements, system activation, driver interface specifications, and test procedures are specified, with backing event duration defined as meeting speed of 16 km/h, distance of 10 meters, or duration of 10 seconds.

Proposal to add Component and Separate Technical Units (STU) approvals regulatory supplement to UN R158 for devices for means of rear visibility or detection. The changes do not affect the content stringency and keep current UN R158 type approvals valid. The proposal replaces the complete UN Regulation text due to the number of changes required, incorporating text merged from Supplements 1 to 6 into the original text, with tracked changes and comments marking modifications outside the direct scope of the SIG-C&STU typical for clarity, corrections or consistency items which shall not affect stringency.

Proposal to consolidate definitions applicable to both Part I and Part II into a single chapter, add component and separate technical unit requirements to Rear-View Camera Systems and Detection Systems, establish requirements for software update references and identification, and merge amendments from Supplements 1–6 into the original text. Current type approvals remain valid. Changes do not affect stringency or content requirements.
