Proposal to clarify that in the case where telltale No. 1 (Master lighting switch) and telltale No. 19 (Position, side marker, and/or end-outline marker lamps) are combined, the symbol may be shown in other colours than specified in the table of telltales in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004 (i.e., per footnote 18 to the table).
39. The expert from OICA introduced GRSG-112-24 to clarify the application of footnote 18 in the case where tell-tales Nos. 1 and 19 were combined. Some experts were of the opinion that footnote 12 already offers that possibility and that the proposed amendment was superfluous. GRSG agreed to take a final position on this subject at its next session and requested the secretariat to circulate GRSG-112-24 with an official symbol.
