Bulb replacement
Bulb replacement is a lot easier to-do!, no need to-do all this removal
Removal is only if you are replacing the whole unit, or like me, cleaning the light up from corrosion and to aid my visual pleasure
To replace the bulb, simple park the car securely on the kerb, ensuring its secure and you can now stick you head and arms under the bumper
On the back of the light cluster is a black cap, simply twist 1/4 turn
this will pop off exposing a few wires, which need disconnecting, a simple clamp holds the bulb in place
release - remove - refit - clamp - connect up - recover DONE
As far as i'm aware, the fog light is a h3 bulb, but please double check before purchasing a new bulb, I will try to add a video of replacement, to show how to-do it
