Hello, I have an 04 Pacifica. It's loaded with just about everything. It has the OEM HID lights. My question is I'm looking for new light assemblies but I'm not sure if I should buy the standard housing or the projector housing. How do I know which one to use. I want to keep the car as close to OEM as possible and this was the very first year Chrysler tried the HID lights but not on all Pacifica's. Thanks for any info you can supply.
