well if you read the first page its basically about moving the fliment from the HID to a lenght that is the same of the stock bulb ( in my case a 9006 ). from the fliment of a 9006 to the housing is differnt from the HID's.
my issue with my HID is that they are not bright enough, I bought them from DDMtuning, they are the same brightness as my slyvania ultras...
I just don't understand how you exactly move the filment in the HID bulb.
