Where I’m from in southern USA, there are 65mph state highways with 4 way traffic light intersections. There is always a “stop light ahead” sign, and the rule is simple: if you are traveling the speed limit and you pass the “stop light ahead” sign before the light starts to change, you will clear the yellow phase.

In Idaho, where they also have 65+ mph highways with traffic light intersections, they have the "stop light ahead" signs, but instead of having long yellow lights, there are lights on the "stop light ahead" sign. (The lights on the sign will start flashing several seconds before the traffic lights change to yellow.) The rule is basically the same though, if you pass the sign before its lights start flashing, you'll make it thru the intersection, otherwise, start slowing down.

We have these in places in Florida. I still slow down (but not slower than the posted min) through these intersections. I've seen way too many accidents on these types of intersections to trust anybody.

Driving in Canada was the first I've encountered stop lights on such a high speed road (I think maybe it was less, perhaps 50mph). I have to say it felt pretty crazy. However, the same situation in the UK would have a roundabout with half a mile of yellow warning lines on the run up to it.

In Texas, if you pass the stop light sign, you hit the gas, turn on the high beams, and pray to jesus it doesn't turn.

That's clever, I wonder how well known it is though.

Some municipalities have been busted for reducing their yellow light times to get more tickets.
