Light Anti-Theft - How are you protecting your HIDs?

So I just purchased some Rugged Ridge red ring HID lights that bolt onto the bumper. Retailing at around $200 a light, I would hate for them to get stolen so I'm thinking about investing in some light locks.

Which of these from the links below is a better lock? What locks do you use or what better methods are there to prevent light theft?

Light Force

I've searched other threads but I still want more opinions and other ideas so let's get a poll going.

Where do you get these & how do you use them? I like this idea.

 

There's a few different off road sites that offer these depending on the thread size your lights have. Mine are 10mm threads and I know that KC lights use 1/2" threads. The locks just replace the standard nut and they lock with a special key that's included. Just google "10mm light locks" or "1/2 light locks" depending on your thread size. KC and Light Force locks are around $30 and the PIAA ones are more expensive at around $40.

Just went ahead and ordered these for $29
