I‘m guessing you mean the eu (french) and the uk made, well the uk one comes complete with mini led indicators and is plug&play in as much as the loom plugs directly into the original one.
The french one uses your original indicators and of course god knows how much tax, import duty etc…. So whilst not cheap I think the uk one does the job nicely.
Super easy to revert to standard but there are no instructions,but you don’t need NASA to install.
As said I’ll post some pics possibly tomorrow (decorating today) and then you can see for yourselves.
