To make a long story short, I have a non-communicating neighbor who's security light goes on every time I go outdoors at night and blasts into my backyard, hence making sitting out there at night and watching the stars a privacy invasion. Obviously, just an adjustment to the direction of his motion/heat detector to limit it to his own yard would be the answer. However, given the nature of the man, do any of you electronic bright guys know of a simple way to defeat it. I wondered about some sort of appropriate reflective tape on one of those whirling garden windmill flowers that you stick in the ground. Just something that would turn it on more frequently than he'd like. I'm sure I'll gain his respect. Thanks for any thoughts and ideas.
