I do not know if the pieces are glued together or not. The display can be disassembled for access to the set and lights if desired; included instructions walk you through the process.
There is a functioning array of lights at the base and above the set. They are powered by replaceable "d" batteries, and controlled by a power switch on the back of the display. A sensor on the front of the display triggers the lights; they have a programmed display that mimics spotlights and flashbulbs. All lights appear to function properly. This is a wonderful display piece for the LEGO collector.
