Yes I've searched, and no there's no GOOD information.

How does one properly adjust JDM headlights on 4th gens? What guidelines should be used for getting the correct beam angle?

 

well for one thing the beam is pointed in the wrong direction. Its's pointed to the left at on coming traffic and there's not much you can do about that(some thing about the way the light was built) but I belive you can adjust the haedlight just like a usdm one
