Just buy a cheap driveway sensing light and tape over the light sensor
that detects day light so that it works all the time.. wire something
to the 120v circuit that also turns on the lights.

Radio Shack used to sell those lightbeam sensors.
Just do not wire it to a shotgun, as if the burgler reamns alive,
your net worth will become his and you will wind up in jail (and not him).
And if he dies, his relatives become rich and you in jail.

From another newsgroup, sign on a hunting cabin:

Set guns are illegal
So is trespassing
I've made my choice
Now you make yours
