Passat b6 sedan - Replacing the left headlight with the original

Hello, I have a problem, that my left headlight is a replacement for a piece that was founded so that it was ... I want to buy a second original drug, hence my questions:
How not to fall for an Englishman?
What companies produced the original hella? Valeo? Any other?
What to pay special attention to ?
What's with this lens? Because some describe it in descriptions and others not on forums, some write that the brightness of the light depends on its condition, how does this relate to things? How to check?
There are ordinary bulbs in my Passat, not xenon ...
I am asking for help because I am green in this topic and the cost of PLN 250-300 in this case is not PLN 10-20 ...

with this original it looks strange, I undressed a few such passaacików and so hella happened rarely and most often it was ordinary on h7 and valeo is usually torsion bixenon, although it does not always seem to me that it was dependent on the version. It's best to check the second lamp you have and buy it because if one is hella, the other valeo will be visible. buy what you have unchanged and that's it.

I just have a valeo, but on the usual h7, what is left to me is allegro, and that if someone in the description writes that a European, that it will be, not Angol ...: /
