Just to check, around my area (the Deep South), it’s 3 headlight flashes to warn of a police check-point/speed trap/etc. Is that the same as everyone else’s system?
Unfortunately, in Yankeeland and elsewhere they suffer from the usual dearth of manners i.e. flashes are all too rare.
In the South the light-flashers are quite reliable, although in the bigger cities where, ahem, interstate migration has occurred the light-flashing standard has slipped badly.
I also recommend the Waze app for smartphones. GPS/Navigation, traffic conditions/reporting by users including road hazards, weather, accidents and....Johnny Law.
Out on the left coast it is only one flash most of the time, although 2 or 3 is possible. Bottom line is that one is enough, more is just icing on the cake.

Recently, here in the SF East Bay, I came upon a county dump truck parked along side of a road well-known as a CHP radar speed trap. Just as I was passing, a hastily drawn up “cardboard sign” came out of the driver’s window which said “Cop with Radar Ahead.” Evidently the driver was having his lunch and performing a public service at the same time. Wonder if that was “free speech” too?
This isn't just to notify oncoming drivers of a cop, either. It's used to warn of any hazard .....in my neck of the woods it's used more to warn people of deer or loose livestock in the road.
In some states you tap your foot in the stall of a public bathroom - just give it a shot
