In theory,could one light with a pir sensor be used to trigger another light that had no sensor?

Yes.

Agreed. And you can also use a remote pir hidden somewhere to trigger a light that would normally be well out of range for a built in pir. Like at the start of a path for example.
Or to trigger shotguns when the TV licence bods are coming up your path...

I don't have a problem with the tv licence people.
I have seen pikey activity locally.

And you hope that if you leave them some fancy lights outside to steal, they might spare your dog, car and slates?

Insecurity Lights are not the answer… a 12 guage and double odd buckshot is.

Double-odd? Is that like a mong tranny or something?

Or have you been watching too many American television performances, and been misled by their strange habit of pronouncing the number '0' as 'ought'?

When the PIR stuff first came out a mate of mine used to take great pleasure in moving around a remote PIR that triggered a row of the smaller flood lights. So the game was to try and sneak up to his front door without setting them off.

With pikey's in the area you could camouflage your property by having a stripped escort mk 3 in the front garden along with some over flowing bins and a pile of old prams and other metal. Then they'd think you were probably related to them and leave you alone.

The proprietor of my local firearms emporium always refers to it as double-odd.

Wouldn't bother with the lighting, they don't need it ... they're used to laying a gravel drive in the dark.
