Dear Ms. Black:#This is in response to your letter of March 29, 1976 concerning the requirements of Federal Motor Vehicle Safety Standard No. 101, *Control Location, Identification, and Illumination*, for identification of the headlamps and taillamps control.#Your letter presented two symbols specified by the International Standards Organization as alternative for identification of the master lighting switch. One of these appears in Column 4 of Table 1 of the standard and the other does not appear anywhere in the table. The headlamps and taillamps control (master lighting switch) is required by S4.2.1 to be identified with the word 'Lights'. The manufacturer may supplement this identification with a symbol, but only with a symbol that appears in Column 3 or Column 4 of TAble 1. In issuing the amendment to the standard published July 29, 1975 (40 FR 31770, copy enclosed), the National Highway Traffic Safety Administration considered both ISO symbols and decided not to permit the one that does not appear in the table.#Yours truly, Stephen P. Wood, Assistant Chief Counsel;
