Hi, i just put in new headlights into my 95 civic coupe. they are just stock, needed to be replaced. So anyways, how do i go about aiming them correctly? Is there any easy procecedure to follow? i think each headlight has 2 screws? do i just turn these with a flat head? also, like how many feet do i need to stay away from the white wall and how do i know if they are correctly adjutsed? thanks
