either get the real jdm ones shipped from japan sellers on ebay: they are one piece headlights not two piece like US ones, they come in black or chrome, and they have 3 horizontal lines on the front
or
get the fake "jdm" ones on ebay: look similar to the real ones except they dont have the lines on the front and u can get them with amber corners
only problem with real jdm ones is u have to either splice into ur connectors or buy a adapter cuz the bulbs are h1 not h4(9006), i would go with one of those two cuz herd the ebay projector/ halo headlights have horrible output and are plain rice... hope that helps
and retro fitted headlights is puting projectors into our headlights meaning u cant buy them cuz they are completely custom, best output but most expensive..
