18. The expert from OICA introduced a revised proposal with a view to defining and describing the operation of the external status indicators for vehicle alarm systems, alarm systems and immobilizers, as contained in Regulations Nos. 97 and 116 (GRE-77-25). Several experts reiterated their concerns that the proposed text, on the one hand, stated that such indicators were not considered lamps within the scope of Regulation No. 48, but, on the other hand, introduced requirements for the indicators. In the absence of a consensus on the issue, the Chair decided to postpone its consideration to the next session.
