Is it possible to adjust my own headlight position on my Honda Accord?

I have noticed that my driver side headlight is obviously facing a bit lower that the passenger side. It is not that much lower, and the adjustment would be minute, maybe less than a milimeter. I have gotten used to it, and sometimes I even resort to my brights(when there are no other cars around, obviously). I just feel like it has been too long and it is unsafe. I do not have the money to go get them re-adjusted at a dealer(someone told me it can be like $100). Do I have any other options?
