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.
