I have them and unmodified, you can notice the beam pattern is shifted over to the left some but it is not very significant and does not hinder night time driving in any way. For those that think that oncoming drivers are blinded (I have seen those comments here before), I don't believe that to be a problem. In fact, I think those here that buy the aftermarket HID kits do that more than with the JDM Xenons. I have yet to have an oncoming driver flash their high beams to me with the JDMs vs. when I had the aftermarket HID lamps where I got flashed all the time. The JDM Xenons are designed for HID pattern and have a cut-off line which prevents the oncoming driver from being "shined" on.
