do a search for the usdm headlights...or just go to the gallery.
here are some jdm headlights:
you can see that the jdm headlights have less space between the outter edge and the projector. usdm headlights have about 1.5-2" worth of space there. dont ask me why, but they just do.
ps. these are pics of my headlights. if you wanna buy em, lemme know.
