Unless I'm missing something or there is more to the code, it says nothing about allowing a single flash as a signal to pass, or that anything else is a violation. The only place a single flash is refered to is in a previous post, not in quoted code. Unless there is more or other code involved here, it seems like the LEO(s) involved in writing these tickets are extending enforcement to their own intrepretation. No (stock) car or truck has EV style lights, no laws broken. I have yet to see where a law or code that has been posted or refered to here states that a driver MANUALLY flashing his/her lights is a violation of any kind.
