Proposal to amend para. 4.5.5.(d) to clarify that stop lamps, direction indicator lamps, reversing lamps and side-marker lamps shall not incorporate a manufacturer logo. The amendment addresses an unintended gap in the regulations whereby side-marker lamps could theoretically be approved with a manufacturer logo, whereas it had never been the intention of GRE to allow side-marker lamps with a manufacturer logo. Contracting Parties agreed during the April 2026 session that an amendment to clarify this would be appropriate.

FIA expresses concerns about logos on side marker lamps, stating that distraction in road traffic is a main reason for accidents and injuries. From a traffic safety perspective, there is no need for logo presentation on light sources or lamps, as their primary function should remain strictly focused on visibility and safety. FIA recommends that if Contracting Parties see a need for illuminated logos on side marker lamps, these should appear in a size not visible on moving traffic, only from close distance, with a maximum total size of 4 cm.

Proposal to amend para. 4.5.5. to permit the internal structure of optical components and the texture of the outer lens of a lamp to incorporate one manufacturer logo built by transparent or non-transparent components, subject to conditions: only the logo of the vehicle manufacturer or body manufacturer brand name is allowed; the enclosed light emitting surface of the logo shall not exceed 100 cm²; graphic marks, emblems, words, or combinations smaller than 5 cm² are not to be considered as a manufacturer logo; the logo light emitting surface does not have to be symmetrical; and stop lamps, direction indicator lamps, reversing lamps, and side-marker lamps shall not incorporate a logo unless the rearmost side-marker lamp is grouped, combined, or reciprocally incorporated with the rear position lamp.
