Bathroom Occupied Signs

[Billct2]

I'm looking for "Bathroom Occupied" signs, but not just one of those sliders.
This has to work like a PortaLet sign where the sign shows "occupied" when someone is actually inside. But it's for a standard interior door.
Any sources?
Thanks

a lock usually does the trick heh

Yea, but these doors can't be locked for "safety" reasons, it's in a school.

even the porta-john ones are associated with the occupant locking the door...

Well some searching found that these are called amoung other things "Bathroom Slider Lock with Indicator". And they are available mostly from large industrial lock/hardware suppliers. The locking is an issue but if they really can't have them locked there are deadbolt styles where I could remove or cut the throw bolt and just have the sign operate. The things you do for good clients.

Make them for the kids to understand....

That would be great! I'd love to do something along those lines to make the kids pay attention.
I'm actually trying to find ones that are a little bigger than usual, but so far the selection is limited.
