the dealer or an auto hook up shop. One question though, why do you need a brand new HID? Hids shouldnt burn out like that. I think you should take it to the dealer and let them replace it and check the system if the HID is burnt. If you messed it up, you might as well get a pair of phillips 6000k bulbs, because different brands hids usually dont match, and for the price the dealer will sell it, you can get the 2 6000k ones.
O.G.
If I were you, I would go to the dealer to let them give you a new bulb cause it should be covered under warranty. Then you should go and buy the 6000k.

They are not bright, in fact they are a little less bright than the stock ones. The higher the temp. the bluer the color. If you ask why the HIDs on an X5 are bright as hell and are blue, that's probably because they have projectors.
