Clarification of the meaning of pair of lamps in case of a design like a band or a strip. “one or more lamp(s), used for the same function, extending from the left- to the right hand side of the vehicle, is (…) considered a pair.” “A pair, constituted of one or more light emitting surface(s), extending from the left- to the right- hand side of the vehicle, shall contain at least one light source on each side.” “Interdependent lamp system” means an assembly of two or more | At least, one independent light source on each side. An interdependent lamp system (Y-lamp) may be constituted of 2 or more lamps. Some configurations which can be allowed by the proposal:  | |
| 2026/07 Rev.1 | R48 S6,7,8 & 9 | Proposed by GTB: “No account shall be taken of retro-reflective devices, retro-reflective markings, lighting devices fitted for the interior lighting of the vehicle and nor of reversing projections. | Already addressed during the previous session.
