Just got done through the same process on my '95 GS.
There should be 3 screws holding a plastic cover on top of each headlight, remove those. Then there should be about 3 bolts holding each lamp in place, remove those as well. Then comes the pain in the !Removed!, which is removing 2 nuts (10mm I believe) vertically holding the outside corner of each lamp. To remove these, you'll have to go to the lining under the wheel arch and pull back the lining closest to the outer edge. You do have the option to remove the tire, but I left it on. The 2 nuts holding the lamp should be directly behind the lining.
Good luck, and if you have any other questions just ask.
