The whole bezel surrounds the instrument cluster, 4x4/headlight switches, radio, HVAC controls, etc. The bezel as Mac has described is the first step to taking off the HVAC control head. The control head is in there with a couple 4.2mm screws (7mm heads).
As for those lights, you may be snookered. I don't think there are any serviceable lights in there. I may be wrong, but I don't think I have seen any.
May want to check a service manual (found free at most librarys, or just ask here and someone may be nice to ya) before you go through the process.
