Today I got my new low beam and high beams mounted, but when I went to a shop to get them adjusted they said that the bulb was not perfectly aligned in the projector.

Do you have to align the bulb that good?
Because in my projectors there is a prism so in my opinion it doesn't matter if the bulb is just a fraction off.

check the bulb for the low beams, it may fit a little lose, if it does check the how to section and take a look at how to install HIDs on your JDM projectors, that's covered on that discussion.

Thanks for your reply Culpable, but I already fixed it.

The mechanic didn't fit the bulb the right way, so back home I took a good look and discovered that the lever that holds the bulb in place wasn't correctly fitted.
