Exposed fixture means and associated mounting features constituting a broad range of structural, aesthetic, and/or functional enhancements to existing recessed fixtures. Embodiments are generally configured to couple at a structural surface at and/or surrounding a recessed fixture. A mounting ring provides secure attachment at the structural surface, a ring cover typically engages with the mounting ring in a twist-lock engagement. An exposed fixture means (EFM) may be coupled at a side of the ring cover opposite the mounting ring. A system of correspondingly configured latch members of each of the ring cover and mounting ring enables relatively universal coupling of different EFMs at an already installed mounting ring. EFMs include a wide variety of aesthetic, functional, and/or structural embodiments.
