Dear Mr. Johnson:

This is in reply to your letter of July 9, 1999, with respect to the "Safe-T-Stop" lighting device. We appreciate your enclosing some materials to help us in answering your question whether the device is permitted under Federal law and regulations.

According to a document by SafeLite of America, Inc., that you enclosed, its product Safe-T-Stop "will pulse [the center high mounted brake light] for approximately 6 seconds and reactivate if the brakes are reapplied." You read S5.5.10(d) of Federal Motor Vehicle Safety Standard No. 108 as requiring "that the third brake light must be wired to be steady-burning," and that you believe that Safe-T-Stop "contravenes this requirement of the standard by varying the brightness of the light."

We confirm your interpretation. S5.5.10(a), (b), and (c) list the motor vehicle lamps that may flash when they are operated. No stop lamp is among the lamps listed. S5.5.10(d) requires all other lamps to be wired to be steady burning, thus including all stop lamps. Standard No. 108 does not allow a stop lamp that pulses, and a vehicle with a stop lamp that pulses does not meet Federal requirements.

The installation of the circuitry that transforms a steady burning stop lamp into one that pulses may violate Federal law. You wrote that Safe-t-Stop is being marketed to consumers by new car dealers in their new car sales. For example, Federal law (49 U.S.C. 30112(a))prohibits a dealer from selling a new vehicle that does not comply with all applicable Federal motor vehicle safety standards. Thus a dealer who sells a new car with Safe-T-Stop installed has sold a vehicle that does not comply with Standard No. 108. Our statute provides for a civil penalty of up to $1,100 upon a dealer for each violation of Sec. 30112(a). A dealer who allows a test drive without sale is also in violation of Sec. 30112(a) which prohibits any person from offering for sale a nonconforming motor vehicle.

The letter of May 11, 1999, from Steven D. Kohn to Maryland's Motor Vehicle Administrator, Anne S. Ferro, which you enclosed, is incorrect in stating that Safe-T-Stop is permitted by S5.1.3 of Standard No. 108 as an "enhancement for existing vehicular brake lights." This provision of Standard No. 108 prohibits the installation of motor vehicle equipment that impairs the effectiveness of lighting equipment required by Standard No. 108. However, when installation of equipment creates a noncompliance per se, as Safe-T-Stop does with S5.5.10(d), S5.1.3 is not applicable.

You state that Mr. Kohn has clarified that, instead of S5.1.3, he is relying on our interpretation of July 24, 1989, to Robert Knauff, and that you do not view this interpretation as supporting his claim that Safe-T-Stop is consistent with Standard No. 108. The 1989 interpretation dealt with a single pulse of light approximately 40 millionths of a second in length which acted through the center high mounted stop lamp as an advance warning of braking before the brakes were applied. We read Standard No. 108's prohibition against combining the center lamp with any other lamp as applying to the collision avoidance pulse, and stated that it could not be furnished as part of a center lamp system. We did say that if the device met the test of S5.1.3, it would be an acceptable addition to any motor vehicle not originally required by Standard No. 108 to be equipped with one (i.e., in 1989, passenger cars manufactured before

September 1, 1985, and all other motor vehicles). Since our 1989 interpretation, vans and light trucks have been required as of September 1, 1993, to be manufactured with the steady burning center stop lamp. Therefore, dealer installation of Safe-T-Stop on new vehicles of these types is subject to the same prohibition as on passenger cars, and to the same civil penalties of up to $1,100 for each violation.

We note Administrator Ferro's reply of June 8, 1999, to Mr. Kohn in which she states that Safe-T-Stop can be accepted in Maryland if "the device is installed as a supplement to, not a replacement of, any center high-mounted stop lamp already installed, consistent with" Standard No. 108 and our 1989 letter.

This letter to you makes clear that Safe-T-Stop cannot be installed in an existing center lamp. To the extent that Ms. Ferro's letter can be read as an approval of a second center lamp incorporating the pulse, this is inconsistent with S5.1.3, as we believe a flashing stop lamp could create confusion and thereby impair the effectiveness of the steady burning stop lamps. Under the U.S. Constitution and 49 U.S.C. Chapter 301, Federal law would govern.

Please note that Federal law also prohibits a dealer from installation of Safe-T-Stop on a vehicle after it is sold. Under 49 U.S.C. 30122, a manufacturer, dealer, distributor, or motor vehicle repair business is forbidden from making inoperative any device or element of design installed on a vehicle pursuant to a Federal motor vehicle safety standard. Because installation of the Safe-T-Stop would create a noncompliance with S5.1.3 by creating confusion and impairing the effectiveness of the steady burning stop lamps, we regard this as a "making inoperative" within the meaning of the statute.

We are furnishing copies of this letter to Administrator Ferro, SafeLite of America (the manufacturer of Safe-T-Stop), Mr. Kohn, and Paul Jackson Rice whom Mr. Kohn represents is his counsel. If you have any questions, you may call Taylor Vinson of this Office (202-366-5263).

Sincerely,
Frank Seales, Jr.
Chief Counsel
