Does anyone know if there is a major difference between the european and us versions of the quattroporte headlight. I need a new headlight and can get a european version, but it has a different part number from the us part numbers the US dealerships use. Is the light the same-or even just the same headlight unit, but it needs a US bulb, that can be bought and installed. Basically I need to know if I can buy a euro part # headlight and if it will work with my us version 08 quattrporte? even if I just need to change out the bulbs I'd be ok with that-does anyone know? They look exactly the same, they just have different part numbers (so far as I can tell), and maybe use different bulbs (US says xenon, and Euro says bi-xenon), but as long as the bulbs are interchangable, i'm ok...please let me know. Thanks
