Help required Please

[greg dear]

I have noticed today that I have water ingress into my driver's side front fog light, in the right side of light from top to bottom ( no visable sign of any cracks in the  glass). managed to take of the black plastic next to light, but retaining screw for light is not moving so have put on some wd 40 and will see if its any easier tomorrow
Is the fog light a sealed unit ? I can see in the Haynes manual that when you change the bulb there is what looks like a rubber cover at the back of light but as is with Haynes  there is only one picture
so has anybody had this problem  is it fixable or  or do I need a new fog light my omega is the pre facelift  thanks Greg
