Even normal lights, with signage that tell you that they make it your turn, are still having you assume the risk that the relationship between the crossing light and the crossing right is still present in the local traffic laws, they just aren’t so transparent about it. The car drivers aren’t taking their cues from the signage but from their beliefs about the lights.
I suppose if one believes the local authorities are drawing these fine distinctions, we might suppose that if the local laws did change, a philosophically-committed sign might be changed faster than a non-committed one, and therefore we might have slightly more confidence that one has the turn when crossing at those lights. It seems like a small effect.
