Need to change fog light bulb in my 97 mitsubishi 3000gt and cant figure out how to help please

Firstly remove undertray from front bumper approx 15-20 screws 2 of which are screwed into either side of the inner wheel arch near the bottom, you should then be able to see the back of the fog lamp. On the back of the fog lamp you will see a black circular shaped peice of plastic, turn this anti clockwise then remove, you will then see a metal clip holding the bulb in place this unclips from one side and you can then remove the bulb and replace with a new one.
