Have any of you seen a traffic light go out (or come back on) in front of you?

Good topic.  This is what I observed.

1:30 a.m. - (My neighborhood in MD)  Main street green, Side street red.  As this is the beginning of flashing mode, the main street transitions to a solid yellow, a very brief red and then a flashing yellow.  The side street flashes to red as soon as the main street flashes to yellow.

5:30 a.m. - (My neighborhood in MD)  Main street FY, side street FR.  Main street goes solid yellow, very brief red, and then green.  Side street transitions to solid red as soon as main street transitions to solid yellow.

Ramp meters.  In CA, some ramp meters are 3-aspect and some are 2-aspect.  Sometimes both are displayed at the same time, with the 3-aspect up high and the 2-aspect at eye level.  When a meter first comes on from no-power, it goes green, yellow, red (like a normal signal with relatively normal amount of time for each phase).  Then, it goes red-green relatively rapidly (at the metering rate).  When the meters go dark, the signals simply turn off after the last brief green aspect.  So the only time I see a yellow signal on a meter is during the off-on transition.

[The ramp meters that they have recently introduced in MD do not go completely dark.  They flash yellow when not in operation.  I don't like it because there is nothing to be cautious of when going down a normal ramp.  Also, they are confusing, since there are flashing yellow beacons at the entrance to warn of the metering lights.  So one has to really be paying attention if the flashing yellow means that the metering is on (at beginning of ramp) or that the metering is off (in the middle of the ramp).  I simply don't like it, and so many states like CA that have had ramp metering for years do fine with simply turning the meter lights off in non-busy times.]

Saw the signal at NY 277 and NY 354 go out and come on again back in December.

I went thru without stopping. And I still am not sure what the Rules of the Road suggest to do in that scenario

Rules of the Road have nothing to suggest for you...that scenario should never happen. Even if transitioning from a red flash to stop-and-go, red and green should never be displayed simultaneously in the same signal face (5-section PPLT heads notwithstanding).

I seem to recall the driver's manual for Oklahoma stating that any malfunctioning (including dark) signal is to be treated as a four-way stop. If I were to encounter this particular failure mode, I'd stop and then proceed only when it was clearly safe for me to do so.
