That and have a Kukri handy like I do

What alarm circuit ?

It's a Tdi Deefer (and a GU Patrol ute)

Thats what i do but i drill the nut aswell..Sometimes i just drill the nut & tap it for a grub screw.Works for me..

if you drill through the nut and driving light mounting bolt and punch in a roll pin, wont the bolt just break off across where the hole is drilled when slimebag applies tool of choice, they are not exactly high tensile bolts. the roll pin is going to be the strongest part of the assembly and will help shear the bolt.

I still vote for the Trunk Monkey

how about using a proximity switch or touch switch and electric fence energiser, why not energise the whole car - not just the lights.
should be fine on a Tdi , (might fry a chip or two on anything modern) probably still go the Trunk Monkey on a Td5

They don't usually use tools.

A sharp tap with the palm of the hand on the lens / body of the light in the right direction will often be enough to "crack" the retaining nuts loose. Then spin the nuts off by hand. A roll pin is enough to prevent that.

Why don't you just tie your dog to the bullbar?

Or if you don't have a dog, borrow one! Or get yourself one - thieves wont steal a pair of lights from behind a bull mastiff!
