Dear Mr. Fujita: This is in reply to your letter of October 17, 1979, asking for a interpretation for Paragraph S4.3.1.7 of Federal Motor Vehicle Safety Standard No. 108.; S4.3.1.7 says in effect that a front turn signal lamp and a low bea headlamp may be closer to each other than 4 inches 'if the sum of the candlepower values of the turn signal lamp measured at the test points within each group listed in Figure 1 is not less than two and one-half times the sum specified for each group for yellow turn signal lamps.'; You have asked whether a motorcycle turn signal lamp should 'satisf the values specified in S4.3.1.7 or half those values'. The answer, is, the values specified in S4.3.1.7. Half those values would be 'less than two and one-half times the sum specified ...' and impermissible under S4.3.1.7.; I hope that this answers your question. Sincerely, Frank Berndt, Chief Counsel
