Do you need extra security at your house? Some security experts say that burglars look for unoccupied homes at night, and that leaving TVs on discourages potential burglars. Fake TV is a small device that simulates the flickering lights of a TV when placed near a front facing window of your house. While I applaud the maker's ingenuity, the $50 for one of these would be better spent on a home security system. I suppose this thing could double as a disco light; except, disco is dead.
