I got a question about fitment. First off the USDM lights are 9004’s correct? Will H4 HID’s fit in the spot where they are going for low beam? Are they the same fitment 9004 & H4? But I thought about it and I might as well get JDM headlights and do the HID conversion then so now, what is the size of the JDM headlight ones? H4? But yeah any help would be appreciated, thaNKs.
