ATTACHMT: Attached to letter dated 7/7/93 from John Womack to Reuven Koter (A41; Std. 108)

TEXT:

Thank you very much for the pages from the CFR 49 mailed to me.

Page 233 paragraph S.5.1.1.19 mentions a specific requirement for the flashing rate of the Hazard Light, as per SAE standard J590b. Can you please fax or mail to us the details of this SAE standard or inform us how it can be obtained.

For the purpose of initial fact finding survey, we kindly ask your opinion on the following issues:

1. What exactly are the U.S. regulations, recommendations, driving codes, common practice or otherwise in regard to use, operation, installation or requirements of the Turn Lights and Hazard (Flasher) Lights including their respective driver console's pilot (operation tell-tale) lamp?

2. Is NHTSA processing in present, or contemplating or is NHTSA aware of future planning of changes, petitions, determinations or any rulemaking action in connection to 1 above?

All the above needed as soon as possible at your earlier convenience since we are now involved with a new safety program/product for the automotive industry based on the very same ABWS concept but activating on the Turn/Hazard Lights instead of the Stop Lamps.

By the way, I am aware of the next ECE Meeting of Experts on Lighting, 15-18 November 1993, in Geneva and their agenda. First item on the agenda is the "Regulation No. 48". Are there anymore details or subject/issues to be discussed under this title?

As always we are very appreciative for your help, asistance and cooperation.

Awaiting for your kind reply.
