I call them preemption signals.

That's what they are called.
There's a set of preemption signals here in Tampa.

Although they operate in tandem with the signals up ahead, I have seen them out-of-sync from the main traffic signals as well.

They are very common in the Lower Peninsula of Michigan. When a crossing with preemption signals activates. The Preemption signals go to solid red while the main signals go to flashing red for the street with the crossing and the other main signals go to flashing yellow. I've only seen a few here in Ohio (not in person with the exception of an abandon one that no longer exists).

A unique one indeed, but that signal you're thinking of is most likely the A/C indicator on that relay case. The gate light on the relay case is probably what tells the engineer that the crossing is functioning properly.

I like how they installed pedestrian signals. The line that breaks off of the other line right at the crossing is quite cool too.
-----------------------------
Here is a cool old signal. I don't know what it is for but if I had to take a guess, I would say that it is for the lift bridge and the signal activates when the bridge lifts and either goes off when the bridge has been opened for a while, or when there is a train and/or locomotive there, or when the train crew knows ahead of time that the bridge is up.
