Abstract
An elevator lantern apparatus uses a snap-fit assembly and disassembly configuration where the lantern apparatus includes components such as a tray, a lens, and a control board having one or more illuminating features. These components are configured to assemble through an opening in a surface such as a wall. In some versions, assembly and disassembly is done without the use of tools. In some versions, disassembly of the lantern apparatus is done from the front side of the lantern apparatus by removing the lens to access other components.
