Why?

Nothing out of the ordinary given out that is not known in the public domain.

 

granted,no one needs to know when the doors can be opened...

I think you miss the point, the lights on the banks I mentoined are for the entrance doors not any vaults or other secure areas.

whys it in the front window then..

And in the local banks the door indicators are behind the window at eye (ish) level.
