I lost one of my housings on the freeway and had a hard time finding the style I had. Different than the standard, but not the Euro ones. Hard to find, at least for me. These were a bit closer to what mine looked like. I had to remove the rubber gasket around the housing to get it to fit (2003 330XI) but it worked like a charm.

Not a proper fit

Received as promised by the seller. My cons on this item: 1) the socket holes does not make a tight fit with the light bulb sockets I have. Both issues for left and right. I had to double the o-ring on my light sockets to make it tight fit. 2) The rubbers around the casing was not properly glued in. The rubber sticks out by a few centimeters. Pics attached.

Looks great on my 2005 BMW 325i

Very pleased with the results after I assembled on my car…except the fit of bulb socket to assembly was a little loose on both of them….but I think it will be fine.
