Yes, I mean that no OEM manufacture even makes a 8000K D2R bulb. If you bought some made by someone else. they could be shoddy. The easiest way to find out is to put your stock bulbs back in and see. The two brands that I would stay with are Osram/Sylvaina and Phillips.
As a side not, some places sell bulbs that they say will fit both D2R (reflector) and D2S (projector) sockets. The D2R bulb has a loingitudinal stripe down the bulb, where the D2S does not. If you put D2S in a D2R system you will get lots of glare and a poorly focused beam because that little stripe is missing. All the marketer has done is modify D2S bases so the fit into a D2R system. It will fit, but the function may not be satisfactory.

Yes, I noticed that my aftermarket 8000K D2R bulbs don't have that longitudinal strip that runs down the spin of the bulb. However, the base looks exactly the same as my stock D2R bulb? Im bringing it to the dealer tomorrow morning and let them have a look at it. Im just hoping its nothing major or cost me an arm and a leg. :(
