Ok so i just bought a pair of JDM headlamps. And i need to adjust them. There are three screws for each low beam. There are 2 on the fender side of the lights. And one on the other side at the top. Does anyone know which screw does what? I just need to kno this so i kno what im adjusting.

 

Can't believe nobody replied yet. Just turn on the headlights, rotate one of the screws and watch the beam. You'll see which direction each screw moves the light.

 

i would just fiddle with it until you figure out what's up
