Abstract
An elevator system including a door post having inner and outer sides, and a hall lantern assembly fixed to the inner side. The door post includes a jamb defining upper and lower openings, and the hall lantern assembly includes upper and lower lenses which are resiliently biased to project through the upper and lower openings, respectively, in operating positions of the lenses. The upper and lower lenses have service positions achievable by depressing a lens against the bias, and then slidably moving the lens in a vertical direction, with the service positions of the upper and lower lenses enabling the hall lantern assembly to be serviced through the upper and lower openings in the jamb.
