so, i just bought some new projector headlights. very nice, i must say. however, i have two problems. my main concern is that they are both very "shakey." anyone know of a quick fix?

plus, i think they need to be aimed a little better. they didnt come with any instructions on how to aim or anything, so i figured i would give a shout out on here.

if anyone can assist me, it would be greatly appreciated
