You can replace the ignitor individually with an OEM peice, or replace the ballast/ignitor assembly with an aftermarket one that will be PnP into your D2S housing.
Is that an easy swap?... Have any pics on how to do it?
I think the ignitor is around $300 at the dealership... any idea how much it is OEM?
