Are you certain these switches are normally closed ? The picture of the light circuit indicates they are normally open, without magnet.

You are correct. Almost all of the reed switches on Amazon universally have the NO/NC descriptions backwards. Even the guy who responded to you about his RV steps was mistaken as his application would require a normally closed switch (ie. door opening and removing the magnet would allow the current to flow). I think the big misunderstanding is these vendors (and some people) think the "normal" position is with a magnet adjacent the reed switch. It is not.

Can this be used in a 12v application? I wanted to use ground to trigger a negative input(car alarm application)

Yes, I am also using it for 12V lights. You limit is going to be the 0.5amp load.

Are these waterproof or at least water resistant?

Yes . It is water proof . Just only wires connection for sensor ( over 10'' long) must be in dry area.
