Hello forum members, i have a 04 350z touring roadster dont know to much about the car since i bought it it came with some mods and stuff.for hid question is does this model come with factory hids? Reason why iam stumped is i was going to replace bulb and notice one side was hid and one was factory halogen have no idea why previous owner did that but i would both sides to be hid of course so how would i go about to making the other side hid,what compents do i need also any splicing or would it be better just to buy a whole conversion kit and install it or would there be a problem instaling a hid kit with the car that has hid already on one side??
