A lighting device, comprising a housing and at least one mounting clip. The housing comprises an electrical connection region engageable in an electrical receptacle. The mounting clip is pivotable from a first position, where an end region of the mounting clip does not extend beyond a periphery of the housing, to a second position, where the end region extends beyond the housing periphery. Also, a lighting device, comprising a housing, a trim element and at least one mounting clip. The mounting clip is pivotable, such that if the mounting clip is in a second position and then the trim element is rotated, the mounting clip will pivot to a third position, where the mounting clip engages the housing such that the trim element is biased toward a ceiling or other structure in which the lighting device is mounted. Also, methods of installing housings and/or trim elements.
