1) Unclip the lens (from the front) - three bulbs visible. Centre one is the courtesy light, the other two are the lights controlled by the two switches.
2) In the recess for each of the two lateral bulbs there is a deeper recess - this has a cross-head screw in the base.
3) I suspect that these are to hold the light unit in place.
4) With trepidation, try removing them - the light unit should come away - caution with the wires.
5) Good luck!
