TEXT:
Last December, after preliminary conversations with you, Mr. Paul Rice wrote to us regarding the "Sudden Brake Indicator Hazard Light." We now have progressed in our research to the point of actually prototyping a working unit for further research and study.
One of the operating techniques of this hazard light is for it to flash. Question: What is the fastest flash rate or range of flash rates expressed in "flashes per minute" that are allowed by Federal law?
Please FAX the answer back at your earliest convenience so we may proceed with our experimentation. Thank you for your continued cooperation.
