Apparatus and associated methods involve a light module adapted to mount to an open face of a conduit body. In an illustrative example, the light module may include an electrical interface for making operative electrical connection to conductors disposed within the conduit body. In some particular embodiments, the electrical interface may include an insulation displacement-style connector to facilitate installation and/or removal of the light module. In various examples, the conduit body may substantially conform to a form factor of a conduit body for a conventional conduit system.
