I live in Oklahoma, and have new neighbors across the street that moved in about two months ago. I have recently noticed that on some nights their front porch light flashes on/off at regular 6-second intervals (I timed it over a half-hour.) To my knowledge they do not work, and there are often vehicles coming and going at all hours. When they aren't at home, the front porch light operates as any normal motion-sensor light does. I am VERY concerned as my school-age children and I may be in danger. I have begun writing down make/model/tag numbers of the vehicles just in case. Any help would be greatly appreciated. Thank you.
