The recent problems regarding headlamp conversion, reminds me of my first coupe in 2000.
I planned to drive to France on holiday. Thinking of the black strips that we put on the car lights to prevent blinding continental drivers, I didn't know where or how to fix them on the bobbly lights.
Local FIAT dealer couldn't come up with answers.
So I approached head office in Slough.
As you would expect, they solved the issue immediately.
