The japan spec headlight uses the same connector,is 1/2 pound lighter,and with a little "trickery" mounts up quite nice! The 2 brackets that are bolted to the top clamp just need to be "flip-flopped" right-side to left and left side to right, this lowers the holes in the brackets to fit the japan spec. shroud. The head lamp itself is smaller and shaped different than the US version. I will have more black plastic to mount up in a week or so.
