During the day I flash my hi beams
During the night I use my hazard lights and triple tap my breaks.
If you flash an oncoming motorist at night, they wont think " oh a speed trap "
They will think, WHAT THE HELL IS HIS PROBLEM! I'm going to flash him back!!!!!!!
You should install fog lights if your vehicle didn't come with them. Flash them to your heart's content. I can not think of a code violation that you can be charged with.
Sorry, but the courts have ruled that the use of high beams to warn oncoming traffic is protected under the first amendment.
Flashing high beams is not the same as not dimming when there is oncoming traffic.
I had to flash the high beams on my motorcycle one night to warn a car coming the opposite direction that they should be aware of the deer in the median.
