I got my last set from gms Capri spares, genuine Morrelo with the correct pattern colours etc. They did say they are having problems getting hold of them now. Think I paid £90 for the pair.
Only bought them because I lent one of my mint (2year old) sets to my girlfriends escort bonus to pass the test and it was stolen before I got round to swapping back.
depends how fussy you are, if you just want clean new lamps most motor factors do them for about £10 each.
