27. The expert from Australia wondered whether or not UN Regulation No. 48 allows for the fitment of lamps other than those that are listed as mandatory or optional in the Regulation, or that meet the definition of an external status indicator, for example, low intensity lamps, lamps for emergency service vehicles, and/or other types of status indicators (GRE-88-14). The expert from the Netherlands expressed the view that the fitment of such lamps should not be allowed (“not mentioned, not fitted”). The Chair recalled that UN Regulation No. 48 does not contain provisions on some lamps for which installation requirements falls within the competence of national legislation of contracting parties, for example, special warning lamps under UN Regulation No. 65. The expert from Australia pointed out that he would continue off-line consultations on this issue.
