OD, if you want to try one out, I have the Thule version, which doesn't fit my FRV (but does fit a Renault Scenic), you are more then welcome to see if it fits your car.
Anyways on to my fettling today. Yesterday the sparky came to fit a light on the landing. Upon fitting it he found it wouldn't work. Said fitting was taken down and original rose re-fitted.
I spent last night pondering the issue and this morning broke out the MK V heavy duty multimeter (known as a Fluke to it's friends), a length of flex and a plug.
After checking voltages everywhere, I tried the suggestion I gave to the sparky yesterday, which was "Are you sure it doesn't need more than one lamp in to work?" Sure enough, after fitting 14 halogen lamps it worked! I guess the "transformer" isn't, it's more like a phone carger, i.e. doesn't do anything until it sees a load on it's output side.
This has cost me £200 as Mrs T insisted we went and bought a new fitting. The upside is that TLD now will have a new light fitting in her bedroom
