2005 mazda 3 HID kit help.
 

hello all. my name is dan and i am here looking for some help. Christmas is near and i want to get my girl a set of HID's from DDM Tuning. i am seeking a 35W 6000k HID kit. but i am having trouble finding what i need to make it PNP. so far if i am right i need the H7 hid bulb. now i read something about a D2. but i think im getting confused at this point. . also when i changed her regular non HID low beam bulb it had this adapter on it. how does this work with an HID bulb. if some of you guys can help me that would be great. and thanks for your time.

edit. i would like to add some info. her car has NON HID lights but it has the projector type setup in the low beam.
