You did not get xenon headlights, which are High Intensity Discharge (HID) bulbs. You bought the fake "xenons", which are regular halogen bulbs with dyed envelopes. These produce less light than the stock bulbs, and often burn out much quicker.

A car without factory bi-xenons does not have the proper wiring harness for the bi-xenons. The regular wiring harness does not have the circuits for the headlight autoleveling system. Bi-xenons can be installed, but the autoleveling won't work. Most dealers will refuse to install them. The dealer will have to program the car for the bi-xenons to work.
