just get a new 1 mate,theres 3 screws under the steering wheel holding the casking on.
and as for the fog's,answer is no.dont put them on lol they will and can fine you for having them on..id check all your fuses again mate for your headlights,if they are all intact,cant you just wire them up with your sidelights as a tremp measure? most people drive round with their headlights on when its not really dark anyhow.
OR how about wiring them up (to a live) and put them on a switch inside the car and flick it on when you need them on?
Just a thought
