I have no idea what projectors were used in my headlights because they're a complete kit (XP6054) opposed to a retrofit. The cut-off isn't as sharp as what you'd find in ... say... those used in an S2000 or a TSX, but they do the trick.
I did have my WJ's headlights retrofitted. The original retrofit used single beam 350Z mini projectors, but the light output was terrible. The guy who did the retrofit posted the work on his site and he ended up selling another WJ retrofit to someone who wanted bi-xenons; when that guy decided to sell/ part-out his Jepp, I snagged his retro and sold mine. His used the much larger FX35 bi-xenon projectors. You can see the difference in the projector size below.
