Dear Supporters,

I have just become aware of a National Highway Traffic Safety Administration Letter of Interpretation dated December 13, 2024 which clearly states that auxiliary flashing lights (also known as "supplemental" lights) are illegal.  Here is a quote from NHTSA: "Therefore, because the “emergency warning lights” are not steady burning, they would not comply with FMVSS No. 108 and would impair required lighting."

Here is the link to the Letter of Interpretation: (https://www.nhtsa.gov/interpretations/ncc-241023-001tsei-tima-letter-interpretation-571108-flashing-amber-lights-12-13).

This means that utility vehicles, tow trucks, and emergency vehicles that have switched to hazardous, dangerous and discriminatory LED auxiliary flashing lights are in violation of federal law.

There are many actions we can now take using this information.  I have initiated lawsuits against state agencies and private companies in California.  You can do the same in your state.  You can also contact your state legislator to ask for help or contact the department of motor vehicles.

We are all needlessly suffering from exposure to illegal LED flashing lights on vehicles.  With this December 13, 2024 letter from NHTSA, now we can do something about it.

Sincerely,
