I've seen it myself. One that comes to mind is HKS.

On the approach plate, says when tower closed, GS unusable.



Any idea why the GS is unusable when the tower is closed? I'd expect to
find the GS on the east side of the runway, is that where it is?



I believe ELM switches the ILS from 6 to 24 depending on the wind
direction. I've never landed after midnight when the tower closes, but
I wonder if they leave the ILS on and leave an ATIS message as to which
runway is ILS active? Never thought about it before this thread. I
guess I always assumed they would turn off the approach when the
controllers go home, but maybe not.
