Dear Mr. Moore: This is in reply to your letter of April 7, 1977, asking for clarification of S4.3.1.1.1 of Standard No. 108. Your initial question of December 27, 1976, was not clear to us hence the reason my answer of March 4, 1977, caused you some confusion.; The diagram in your letter of April 7 clearly depicts the exemptio provided by S4.3.1.1.1 for the specific reasons therein, that when a clearance lamp indicating overall width is not located on the rear of a vehicle it need not be visible at 45 degrees inboard. As the only required points of photometric measurement of a clearance lamp so located are to the rear and at 45 degrees outboard, the lamp need not be visible at any point in the 45 degree arc depicted in your letter.; Sincerely, Frank A. Berndt, Acting Chief Counsel
