I am putting a set of XenonPro LED headlights in my 2002 xterra. I have been running Xenon HIDs with the twist-lock retainer for the last 3 years. The HIDs began giving me problems, with a lifetime warranty on them, I'm letting them have them back. My dilemma; I don't recall what I did with my original bulb retainers when I did the install, can't find them. The retainers on my HIDs came with them, besides no way to keep them without cutting them off. Does anyone have a set of bulb retainers in a xterra parts car? If so, please let me know. I have nothing but fog lights now.
