TEXT:

Mr. Joe Rutman Travelite Division Pathway, Ltd. BOX 195 Grand Rapids, MI 49508

This is in reply to your letter of February 11, 1987, providing information about the electronic message display known as "Tellite" which has been developed by Pathway Limited.

I enclose copies of two recent agency interpretations on electronic message displays similar to yours. You will see that under Federal law such displays may not be used as original equipment, or as replacement equipment on passenger cars that carried cen ter highmounted stop lamps as original equipment. Whether they are acceptable as aftermarket equipment on other vehicles depends on the laws of the individual States there the display will be sold and operated.

Sincerely,

Erika Z. Jones Chief Counsel

Re: Pathway Limited

Dear Ms. Jones:

This is in response to your letter of January 7, 1987, regarding the electronic message display known as "Tellite" which has been developed by Pathway Limited.

Enclosed with this letter, you will find the following:

1. A letter from the Company's engineers, explaining certain material features of the display, and

2. Drawings of the display and the handheld keyboard which is used to activate the display.

It should be pointed out that the display can be read from directly behind the vehicle, but cannot be read from the side. You should also be aware that the handheld keyboard only activates the display, and does not program messages.

I am also enclosing the 16 messages with which it is currently intended that every chip will be programmed.

If you require anything further, please advise.

Sincerely,

PATHWAY LTD. Joe Rutman

February 9, 1987

Mr. Joe Rutman President Travelite Division of Pathway, Ltd. P.O. Box 88111 Grand Rapids, MI 49508

Subject: U.S. DEPARTMENT OF TRANSPORTATION LETTER OF INQUIRY

In regards to the questions raised in the aforementioned letter:

1. light emitted by the brake-light portion of the display will pass through the message portion, as the light sources for both portions originate from the same printed circuit board. Red L.E.D.'s are used for the brake-light and yellow L.E.D.'s are used for the message display.

2. The brake-light circuit overrides the message display by disabling and blanking out any message displayed at the time the brake-light is turned on.

I hope the above answers are satisfactory. If you have any other questions, feel free to call.

FRANK HOCKEBORN, PROPRIETOR
