I recently replaced the headlight and signal light bulbs on my car and it is quite simple. This is as long as you are only changing the bulbs. As described in the headlight tech thread if you lose low beam the headlight assembly would have to be replaced.
I removed the inner fender liners to gain access( the hardest part of the job -see threads on this) then removed the evaporative canister assembly on the right side.
Once this is out of the way you remove the small box shaped plastic cover on the back of the headlight, unplug the electric cord (no clips, pulls straight out), remove the screws that hold the retaining strap or the screw that holds the bulb and remove the headlight bulb. The signal light bulb is easier as you give the holder a turn to remove.
Good luck with it. If you would like more information, please reply and I will post some pictures.
