i have removed rear outer bulb cover on focus estate 2007 diesel, via 2 screws, it has a back cover connected which is white covering acess to bulbs, does this come from outer casing by hand force or is there a way to remove to get acess to change the brake light bulb, help thanks. newby.

sorted, pull the electric cable out from housing, there are two screws in the rear white casing, unscrew to get acess to bulbs to change. HOPE THIS HELPS SOMEONE OUT IN SAME SITUATION.
