As far as adjusting goes.
Its 2 Screws if you tighten the top one the Beam goes UP but you also need to Loosen the lower one for this
and if you need the beams lower Loosen the top and tighten the bottom
My night shots have them extremely high which i need to adjust again.
As far as highbeams Its got a Bulb in there but the Highbeams dont come on with a HID kit (Not sure why) but at anyrate the HID's are 10fold more brighter then the highbeams anyway.
