Identify your defensive position(s) in the house at night. Assess the field of fire, what an intruder will be able to see with the lights off and what you will be able to see. Arrange light sources and to reduce former and increase latter. Install low mounted wall switch to turn on blinding lights to transfix intruder. Install deadbolt on bedroom door. Install telephone in bedroom. Close door. Lock door. Call 911. Prowling around a dark house juggling gun and flashlight is really a very last resort.
