You're right; it's been so long that I actually forgot they specialize in bmw parts. The lesson is clear though; don't buy cheap, untested parts for your car that are responsible for control or safety.
Oh, and apparently I misunderstood the last email DDM sent to me because my lights shipped yesterday via fedex; they are not on back-order; they were on back-order.
Photos and such when everything arrives; I will see if I can eyeball a color temperature. The last set of 5000K still work fine and the difference between 6000k and 7000k+ is usually easy to notice.
