If you are going out of town for vacation, or even just the night, it is important to make sure your house is safe and secure from burglars. There a are quite a few tricks that people use as deterrents, such as pausing your newspaper delivery and locking things up. Another trick is to plug in a lamp to a timer in a couple rooms to give the illusion that someone is home. My next invention takes the "timed lamp" one step further.
I propose a light, maybe led, that when illuminated and seen through a window, gives the impression that a television is on. The light would flicker, go bright and dark and basically just replicate the effect that the light of a TV gives off. This is not a very elaborate, expensive or groundbreaking invention, it is simply another trick to deter would-be criminals from burglarizing your home.
I believe this invention would be inexpensive to make. a couple LED's of different colors attached to a circuit board that would generate random color patterns and flickers. The timer for the unit could be programmed to turn on and off at different times of the day and night.
