San Francisco now has white arrows with a red slash through them. They are combined with special right of way signals for bicycles.
Unfortunately, the one I know of is too new to show up in street view (Duboce and Valencia).
The most annoying thing about it, other than the fact that the color scheme looks nothing like any other traffic light, is that the white lights are blindingly bright and your eye is drawn to the big white arrow and away from any other control signal or sign. Yes, you can and should be looking at some of the other devices there, but the white arrow is about 3 times the size of any other signal at the intersection and more than double the brightness. Wait, it's white - is that go or stop? White means walk so wouldn't it mean go? Huh, there's also a red thing there that is also very bright, but can't compete with the white arrow. What is it? A slash? So, whatever I think the white means it's saying don't do the ambiguous thing that was never described in any driver's handbook that I've ever studied... (It isn't rocket science to figure out, but it flies in the face of traffic control devices being simple, recognizable, and obvious...)
