Gidday,
Back to read the responses to my first post, and find that detractors are trying to turn it into a discussion on electronic rust prevention. Thanks for your interest in my post, but I've researched this topic extensively and there are lots of blogs on the net ad infinitum, so if you want to debate electronic rust prevention per se, please go there and do it, not here.
To the detractors; no the Disco isn't a boat, doesn't have an outboard motor, doesn't use magnets and whizzy things, so lets keep this discussion to facts if you want to discuss it further. Rust prevention on water craft and on submerged steel structures is a well understood scientific process that is different and unsuitable for cars, so if you want to read more about that go to the blogs on the net and pick out some of the more sensible responses written by people in the industry who know what they are talking about.
I did quite a lot of research on this before buying the system I did, and while I agree that some of the electronic systems on the market I wouldn't use, the Couplertec and the CounterAct (same system) are the only ones I could find that have been tested by recognised scientific labs, and come with lots of experiential evidence from uses to demonstrate that they do in fact work.
I live in the mining area of Nth Queensland Australia, where our biggest industry is exporting coal all over the world.
The coal mining environment is sulphurous, and vehicles rust out heavily in a couple of years.
The mining companies fit these devices to all their vehicles and heavy machinery, and experience has shown that they definitely do work.
Our State University is one of the labs that have tested these devices, not to prove rust prevention per se, but to demonstrate that they do exhibit an electronic effect on the surface of the vehicle, which would support the premise that it has a rust inhibition effect.
If you want to read about the lab reports, go here:

If you want to see a list of reputable Aussie companies, organisations, and state councils who are happy to put their name in support of this system go here:

If you want to add some snake oil comment about rust prevention, please go elsewhere.
Now to return to the original thread of my discussion:
Does anyone know how to take the back tail light assembly off the Discovery III.
Maybe I should just tug a bit harder?
