I hadn't thought about the solar lights. My son has a couple but he never uses them because they're near the street by a light pole. They were there just for a decoration.
I thought of the idea of the light when I noticed I was playing a computer game and I came to a long hallway. I learned how to clear rooms from Doom, Delta Force[The game, that is] and a class at the Whittington Center.
I read a account of motion detectors from a magazine that said that burgulars fear those than a standard light. They never knew whether or not the homeowner was putting the light on.
Absolutely! Motion triggered lights are HATED by crooks! These can also be mixed in with lights that can be remote controlled, or put on timers. The idea is to keep the "light-dark topography" seemingly random and unpredictable so that crooks cannot plan a long shadowy stalk to your window. At any time in the open, he may suddenly be bathed in light from any direction.
OTOH, lights on a house which are on all the time may be useless, or worse, since they night blind the owner while providing certain dark lanes for the infiltrator.
