I am considering getting HID conversion kits. I have a 2006 mazda 6 sports wagon with the lower mazda sport bumper fog light kit. I want to replace the headlights and fog lights with and HID kit. Which size of bulbs do I need? Do you have install instructions with these and are these something that a semi amaturer can install? I do not want to do any splicing of wires, etc. Thanks.
