Yes, the 12v lights are wired with an earth to the transformer & 2 core out to the lights.
So saying that I'd prefer it if people learned about things beforehand, and acquired a full and genuine understanding of how it worked and exactly what to do before they picked up a screwdriver was exerting my superiority and denigrating you, was it?
The restriction against using G/Y as anything other than a CPC/earth, only applies to single core cables, here is an excerpt from 514.4.2: "Single core cables that are coloured green-and yellow throughout their length shall only be used as a protective conductor and shall not be over-marked at their terminations, except as permitted by Regulation 514.4.3."
Whith multicore cables such as flex, or SWA, it is allowed to oversleeve the exposed core another colour.

To be clear, oversleeving non-insulated CPC is still not allowed.
Somebody else has already posed a similar question in this thread with regards to reappropriating the CPC for neutral, so clearly the answer is not as obvious as it may seem.
Still no guarantee the RCD would trip.
Yes it would, that's what they're for. There'd be an inbalance and the RCD would trip. Unless the touchee is fully insulated.Still no guarantee the RCD would trip.
Indeed, but the theory (hope) is that it would 'if it needed to' - i.e. if there were a path to earth through the person which resuted in at least 30mA flowing!Still no guarantee the RCD would trip.
Think Rf knows how they work.
Where do you propose this imbalanced current will flow to then
Standing on a wooden or carpeted floor its more likely very little current will flow if any.
Therefore as he said there is no guarantee it will trip
Yes, but it is a safety measure.Am I right in thinking that some countries don't include an earth at all?

Tell you what why dont you go back to the screwfix forum, instead of critisizing people here, which is what a majority of your posts are about.

I would reather someone say theres no guarentee of tripping than give them a false sence of security to be honest
John gave the sensible answer
Rf myself and many others have both found peirced cables in situations where touching them would not have tripped an Rcd yet are still potentially dangerous.
Salad fingers , get yourself an insulation tester and go round your home and meggar between 10 points on your floor and a known earthed point and report back
So if you received a 29mA shock for god knows how long you'd walk away absolutely unharmed would you?
