On Wisconsin if you're talking about the lights that are not permanently on, but turn on when a pedestrian crosses the street, the flashing red means yield? There is a big sign on each of the lights that says stop on red and proceed on flashing red. It's really confusing, I drive on this road like 4 or 5 times a week, it took me a while to get used to it. Link below should take you to the sign.
