Just for info puirposes, i did this on my 93 protege 2 years ago, and i did absolutely nohtin to the headlight at all, and the plastic ousing didnt take any damage, and i gurantee u that the protege headlight is alot worse than the contour headlight for yellowing.
I wanted to do it to my contour, but i read abou all this stuff happening and blah i honestly didnt believe it. But nice to see it can be done, cutting it seems like a bit too much work. Cant wait to go out to the pullpart, adn try this out..
Before - when i first got the car

2 years later...:)
