Couldn't tell which car it's from as its used on so many in the Fiat/Alfa/Lancia family. The Alfa 159 and Fiat Panda 100HP I have both use it. There may be differences on mounting bracketry but the points the brackets pick up on the lamp are the same I think.

Guy, it's difficult to see on this photo, but 'Lancia' is molded into the glass. Strange that they do this if it is a parts bin light used across several ranges. I can only think that for the Lancia model it is visible enough to make this worth doing.
