I have JDM projectors and installed a kit from DDM. They don't blind anyone since I aimed them to California DOT specs following this thread posted by ministiguy: http://legacygt.com/forums/showthrea...-do-54740.html
Some people would advise against using HIDs in JDM projectors since there is a possibility that the chrome will bubble. I haven't had that experience. I am running 55w 5000k (maybe 6000k, not sure) IIRC, and they are completely awesome.
I don't even use my brights lately. But I will ground the brights soon so I can run them with the HIDs.
I did the HID install at the same time I installed my JDMs, and also threw in some angel eyes. I also wired the JDMs so I could use the city lights, stock lows, and highs, and turn signals so it took me a while to work out the bugs and figure everything out. As far as installing the HIDs they are really easy to do. I took pics of how I did it and could dig some up if you want.
