We boondock a lot and I have been wanting a fake alarm system. I went to Radio Shack and bought a little flashing red light run by 2 AA batteries. It has a hard plastic case, an on/off switch and a red light that flashes about once every 3 seconds. The whole thing is just a little larger than the two batteries. A whopping price of 3 bucks. I bought 2. We have the velcro stickup buttons. I'll put one by the entrance door and one by the drivers seat. They do not do anything but flash a red light, but I think they will fool a bugler or at least make him move on to a coach without a "security system".
