So I was thinking about a recent thread where a guys firearms were stolen partially due to the fact he left his safe unlocked. Hmmmm what if you put a momentary off push button switch on one of the locking lugs of your safe so that when locked the switch would open a circuit. You then rigged up a simple LED light at eye level at the door or doors you leave your house through. So that if the safe was unlocked you would see a little red light as you exicted the house. Granted running the wires and working out some of the details could be beyond many peoples DIY skill set. But I thought I would put the idea out there. I am planning on using this idea on my firearms storage. If there is real interest in this idea I could draw up and post a simple circuit diagram and find some sources to get people started.
