I am trying to gain access to the light at the pedestal base of my 2000 Hunter 290. I read archives and it said there are two screws to unscrew... I see nothing. I am alos trying to replace bulb in aft cabin overhead in ceiling. Again do not see way to access. Thing is plastic and I don't want to break. I think in both cases bulbs are shot due to condensation/short. Advice appreciated.
