»Should I stay or should I go?

The New York Times has a question: to wit, should I stay or should I go? The question, prompted by the cross-walk signs that simultaneously show the Walk and Don't Walk icons,has an answer: "Call 311" (that's 212-NEW YORK, or 212-639-9675).

My photograph, above, came from a cameraphone and does not adequately show either how clearly the two icons are simultaneously illuminated, nor how prevalent these malfunctions are.
