Hei.
There are two different producers of the headlamp. I can't remember any of them, but they differ on the inside and how the light beam is reflected. I had to change my headlamps due to "corrotion" of the reflectors - the "mirror" chrome paint dissolved and fell off. They were completely matte, and needed replacing. But ofcourse it was impossible to find, and was not produced any more either. So I got a pair of used lamps from the scrapyard. They were another brand, and was different inside, but mounting holes and wire connection was the same.
