TITLE: RE: FMVSS-101

ATTACHMT: ATTACHED TO LETTER DATED 3/07/89 FROM ERIKA Z. JONES -- NHTSA TO THERESA ROONEY, REDBOOK A33, STANDARD 101

TEXT: Dear Mr. Glancy:

I am writing to you on recommendation from Mr. Cavey of the National Highway Traffic Safety Association. He suggested that I might contact you to get written confirmation of our interpretation of the above ruling to be enacted 9/1/89.

It is my understanding that any car sound system which has been factory installed must be equipped with light intensities that have two values, a higher one for day, and lower one for night. These two light intensities do not have to be variable and any color may be used to illuminate the system.

If possible, I would like to receive written confirmation of this correct interpretation from your office for our records.

Any assistance that you may provide in this matter would be greatly appreciated.

Sincerely,
