I guess this is something I should try out once I get some glow sticks (could be a while sodding car is eating my spare cash at the moment) and it's a simple enough system to try and if it works it could give early warning if your running patrols round a large area

Not sure if this would be effective and in a larger area where you might have a night patrol on watch, it might be better if they set off one of those air horn things that you hear at football matches as the sound of them is quite startling to any would be intruders and would alert rest of the commune.
