If the light assembly is like our Windsport aiming might be hard.
Ours have 3 are pieces of angle aluminum with one bolt through each, I think you could adjust left to right and a bit of up and down ( top is bolted to the lamp assembly )I just took some pictures
Looking from the back the blue tape marks where the bolts. The plastic housing is slotted so you can move it about 3/4" at each location .
The 1st pic shows the lower mount, 2nd the back side of the assy.
Hope it helps
