Alligning the headlights

Good morning, can any 1 give me any tips on how i can if any to aim my head lights ? I have a 2001 Grand am. I changed my bulbs and now the right side seems to be aiming a little higher than the left 1 and I am sure the housing for the lights r in properly, and if any 1 can help thx, if not have a good day......later

i just found an open strech of road and brought my star-tip screw driver, just got in and out of my car till the head lights looked good enough.

Thx it sounds like a good idea, but my aiming screws are torx head socket not the male type but the female type...and i am trying to find a socket that fits, anyway thanks a bunch and if any else has any other tips let me know. Peace from Canada..
