Tools you will probably need.

a. Ratchet
b. 10mm socket
c. 12mm socket
d. extension.
e. screwdriver phillips and straight
f. haynes manual.

Ok here goes.... FIRST you must take off your bumper. To do so there 2 bolts behind your bumper lenses, this requires the ratchet, extension and 12mm socket (if its not 12, then try 10). Then open up your hood there are two nuts that are right behind the each of the headlights. you must use a 10mm socket for this.
There are other bolts that i do not remember of, consult your haynes manual for further instructions.

Next once you have your bumper off, you will have access to the bolts for the headlights, use the ratchet/socket combo accordingly.

Once you are done, put everything back together and you're set. I may remind you that once you put it back it may not fit as snug as stock.... do not be afraid.
