Proposal to delete footnote ¹⁸ of Table 1 regarding telltale no. 1 (Master lighting switch) when it is combined with telltale no. 19 (Position, side marker, and/or end-outline marker lamps). The footnote is redundant and potentially confusing since UN R121 already refers to paragraph 5. of ISO 2575-2004 which states, “A given symbol may be shown in more than one of the colours specified in 5.1 in order to convey a change in the operating condition.”

Proposal to insert Footnote 18 for Tell-tale 1 (Master lighting switch) stating, “Symbol may be shown in other colours than specified in column 5 in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004.”
