Dear Dr. Lckemeyer:
As you have requested, we are responding by FAX to your FAX letter of June 25, 1993, to Taylor Vinson of this Office.
Our FAX letter to you of May 28, 1993, provided an interpretation of SAE J588 NOV84, incorporated by reference in Federal Motor Vehicle Safety Standard No. 108. You mention the l990 SAE Ground Vehicle Lighting Manual which refers to SAE J588 September l970, and ask which is the correct SAE reference.
Standard No. 108 was amended with an effective date of December 1, 1990, to substitute "SAE J588 NOV84" for "SAE J588 September 1970" as the U.S. Federal requirement for turn signal lamps used as original equipment on passenger cars and other motor vehicles with an overall width of less than 80 inches overall width. Turn signal lamps may still be manufactured to the requirements of "SAE J588 September 1970" if they are intended to replace original equipment turn signal lamps that were manufactured in accordance with "SAE J588 September 1970." We understand that your earlier letter asked for an interpretation of Standard No. 108 as it related to the design of lamps for future production, and trust that this answers your question.
As you have requested, we are also FAXing a copy of Table III. Sincerely,
John Womack Acting Chief Counsel ref:108 d:7/8/93
