No noise, no traces left, just a lightbulb going dead the supposedly normal way of wear/tear/burning out.

 

 

So, inspect your defective lightbulbs closely when you replace them, they might just indicate modern age Garrett activity.

Just ignore the refrigderator-sized CO2 laser with the 2.5KW amplifier humming and the diesel generator running next to it

Or you could just carry a little hammer and *plink*.

Or you could screw the bulb a bit so that it does not detach, but loses contact?

[demagogue]

I thought of that, but my method has the virtue of not touching the hot bulb! Maybe you can use your sleeve to make contact.

In the EU we've been installing electric light switches for a while now. Sometimes the simplest solutions are the best.

I went to the history museum not too long ago and they had an exhibition on the earliest electricity (it was sort of on the electricity arms race between Edison & his competitors), and I learned that they used to use the metal of the gas pipes to carry electricity to lamps, so they could use existing material & not tear down the wall. So you could use gas or electric lamps from the same sockets. Haha, nothing dodgy about that. Actually most everything I saw in that exhibition would be great fodder for Dark Mod paraphernalia.

Well, the common security sensitive lightswitch is usually well protected. Attacking the evil lightsource directly, especially from afar and silently without much suspicious tell-tale-signs like broken glass and a rock nearby might be more elegant.

 

Also, the CO2 laser in the vid is weak (powered by "neon transformer") and "deactivation time" so is high; I posted because I'm currently into CO2 lasers, because a friend of mine bought a cheap chinese CNC CO2 laser cutter/engraver - the laser tube in that thing is easily replaced (it wears out with time), so we decided to get it out and try to laser stuff "free handed".

 

It's a 40W tube, about 0,8m in length, requiring a high voltage power source (a box the size of a PC power supply). The point is, you can easily operate the whole setup with a battery/power supply from a backpack.

Beam divergence without any optics right out of the tube is nicely low, in 10m distance you get a pea-sized white hot spot on concrete in about two seconds.

 

There happen to be some interesting vids in youtube, search for "co2 laser" and you will find some hobbyists demonstrating their co2 lasers while burning paper, wood, plastics - and glass.

 

And if you have a lightweight portable setup that silently and remotely makes tiny holes in glass, you have a viable modern age water arrow. Just saying.

A real water arror would smash the first bulb, short it out and blow the fuse, so all lights go out at once. That would be way more efficient than a C02 laser - but not as geeky

 

Anyway, in case you missed it, we just made fun.
