Hi Bren - I remember seeing these as a dealer option on Fiat catalogues for the UK market. I think that the idea is great but has been executed in a more symmetrical way for other cars such as the BMW 316 and Mk 1 Gold GTi twin headlamp conversions. Also the Opel Ascona/Vauxhall Cavalier J car Hella grill with integrated spot lamps.
I never warmed to this grill mainly due to the location of the additional lamps - They have been placed low down and next to the main lamps when a more central location may have suited them better, cosmetically speaking. There was a brand new set with lights on Ebay about 6 months ago. Thanks for the suggestion... but I'm planning a different upgrade the front of my Super!
