It's not how they are "aimed".

There is a cutoff shield inside the projector with a dipped portion that blocks light a bit more on the oncoming traffic side. You'd need to disassemble the headlights and flip those shields around so that the dipped portion is on the other side.

Here you can see a generic cutoff shield and the difference in height between the right and left side. You'd need to flip this piece around.
