as far as aiming the projectors go.. the 2 screws in the back adjust the light.. i got mine adjusted really good and this is how i did it...
1. Park your car about 10 feet from a wall where you can see where your lights are shining.
2. Start adjusting the screws... this is the hard part cause there is a lot of right and left turns
.. but if you watch the light you'll figure out how it moves up down left and right.. tedious i kno
3. when you think you have the right adjustment close the hood and test it out... if its not what you want do it again... thats what you get for ebay lights... ive had em for a year and just recently ive taken em out and did some work on em
