Assuming your Pathfinder still uses H4 lamps, meaning, it's just one bulb with two filaments to do both high and low beam, then you'll need to get something that is for "H4/9003/HB2", which are all three names for basically the same thing. There are some slight differences, but for the most part, you wouldn't notice anyway.
What kind of HIDs? well, I prefer Bi-Xenon. This is the kind that uses only one Xenon gas bulb, period. The way it works is, when you flip to high, an electro-magnet switches polarity, and pulls the bulb back a little. If you go to any auto store, find an H4/9003/HB2 headlamp bulb, you'll see two filaments, one further from the base than the other. The far one is the low beam, you should see a shield around it. The closer one is the high beam. Moving the bulb (with a secondary shield) in a bi-xenon kit is supposed to replicate that.
Make sure you get a shield with the bulb you buy.
The other type that gives you high and low beams is usually called a "Hi/Lo Xenon" kit... It uses a xenon bulb for low beam, but you'll have a halogen bulb for high beam. I really dislike this one. The problem is, the second bulb isn't centered, so you're not going to get the focus you need.
Let me put it this way, there are people out there that b**** and moan that you shouldn't use a Xenon kit in a halogen housing because of the light source isn't in the same place and the same "direction." By direction, a halogen's filament runs left to right when you look at the bulb, but a xenon runs up and down. In any case, if what they say is remotely true for something off by a millimeter or two, can you imagine a second bulb that's off by a centimeter? I'd have less issue if it was at least lined up in front, not to the side of the xenon bulb. Now that I think about it, it might not be as bad if it were on the other side. The way it is, the high bounces to the driver side, or in other words, to oncoming cars on roads like in the US.
In any case, the last type of kit are single bulbs for ONLY high or only low. If you go this route, then you obviously are going to lose one... unless you replace the housing with a custom made dual bulb housing. I say custom, because there's no aftermarket part being sold, that I've seen.
Like I said for the bi-xenon, make sure you get a shield around the kit, unless you're going for high only. The shield prevents the low beam light from bouncing off the bottom of the reflector housing... that bottom light reflection is only needed for high beam since it reflects up.
As for where to get them... I'm still working on it... so far, getting them off Amazon isn't helping me.
