If the bits ever come my way (rocking horses spring to mind) then i'll look at doing it properly, but for now, this is better than I could have ever expected 
What like these 

Ah! But Peter, I am looking for FACELIFT front lights you MUNKEH! There are a few old style sets around cos everybody is scrapping those rusty old heaps

Manta - I think we've now answered your question a little better, if you look at those (pre-facelift) front lights (similar to yours) you will see a body coloured strip along the bottom supporting the washer jets....
The facelift lights are a slightly different in the fact that the strip is
separate from the unit itself and is a blank piece, washers are installed in the bumper. Not 100% sure but I don't think they will be a straight forward fit :-/
Hell, i'm not sure at all really! My choice - I would source some cheaper mini-facelift projector style lights (like those above but not Xenon) and fit an aftermarket HID/xenon kit. Job done

Pete, are you gonna do the job properly and install the automatic levelling and washers!?! Happy hacking!
