When I was stationed in Germany, intersections on rural highways that had regular traffic lights often had a special single lense traffic light a couple hundred meters or so in front of the intersection displaying “70”. If the “70” was green, It meant that as long as you were doing at least 70 km/h (about 42 mph) or more you would have the green light at the intersection. If it was red, you weren’t gonna make it. I honestly don’t recall now if there was a yellow “70”. It was pretty handy, you didn’t have to worry about whether you’re going to get right up the intersection and the lights suddenly start changing.
