I'm about to buy the blacked-out headlights and I figure that this is a good time to upgrade to HID. I'm pretty sure that the fog lights use H3, so I'll be upgrading those as well.
My question, however, is what I need to get for the head lights. I know they use a 9007 bulb, but what about high-beam function? Do I need bi-xenon 9007 HIDs?

Thanks

Also, is it pretty easy to remove/install the aftermarket headlights?
