Anyone got a set?  They look good but are they road legal in the UK ?

I have them and they are legal and very nice. Paid a bit less though on ebay...

Any bulb errors ?

None. There are error cancelling resistors built in.

I take it's these LED rear lights are for a facelift model as I don't see any red reflector built to replace the one on a MK2

There's a different one for the non-vrs with an integrated reflector. Best to look on dectane-tuning.com and get the code for the relevant unit, then search that code on eBay or Google.
