Class Action Suit says Florida Highway Patrol Illegally Tickets Motorists Who Warn...

Do you live here in the US or just watch US produced cop/robber shows?

Can you not answer the questions without undermining your position?
I don't think I have seen a US cop show since kojak

No, I said this:

And that reply you gave was to a question about flashing, not about having the lights on while driving.

I was refering to leaving the high beams on while driving. Not flashing.

On top of the above...
Using high beams against oncoming traffic is a violation, the code doesn't specify how long they have to be on for, just how close you can be to the oncoming vehicle before you are breaking the law by using high beams.
