if they are Mk5 Golf ones then no they don't fit facelift FR/Cupra/R bumpers
I used the internals / back parts from a pair of Mk5 and used a pair of original FL front fog lenses. If you have search for my username you will find pics.
Wasn't a major job but not cheap if you don't have access to the parts at trade cost like I did (in fact I got mine free of charge from our lighting supplier)
