I'm a fan of back-lighting. So I keep a bag of roadside flares in the bedroom. As I move through the house I can strike them one at a time and toss them to the back of the room I'm checking....
Seriously, if I really think someone's in the house we will barricade ourselves and cover the door. We can wait for law enforcement to arrive and do any house clearing. The times I've gone out to check on the "things that go bump in the night", I turn on the lights as I go. I haven't bothered to pick up a firearm on any of those occasions. Call me crazy or call me lazy, just don't forget to call me for supper.
