    Dear Mr. Cadoff:

    This is in reply to your letter of October 19, 2001, to Richard Van Iderstine of this agency. As you know, delivery of mail to Federal offices in Washington has been delayed since October because of the need to ensure that it was free of anthrax spores, and we did not receive your letter until January 14, 2002.

    Your letter concerns an electronic "wide turn" LED message sign that your company has developed, called "Right Lite," intended for the rear of large trucks. You refer to a concern with "interference lighting."

    Generally, devices such as yours have been deemed permissible. We are enclosing two letters from this office which discuss this issue with reference to "wide load" LED message signs, the first addressed to Representative Charles Wilson (February 19, 1988), and the second to K. Howard Sharp (June 7, 1995).

    If you have further questions about these letters or our regulations, you may telephone Taylor Vinson of this Office (202-366-5263).

    Sincerely,

    John Womack
    Acting Chief Counsel
