I also installed the HID kit and must say they are bright (5000k).
Adjusting the headlight is a pain.
What I did to adjust was, find a wall on a flat surface, put tape on wall, etc, etc. there is a link here on how to aim your light...
With the accord, what I've done was use a 10mm socket. It's hard to see but if you look horizontally (not thought the hole; because you won’t see a thing) the teeth that you do see are attached to a nut. Use the 10mm socket with an extension and you should be able to rotate it freely.
Anyways it worked for me.
