To remove the trim, you first remove the bulb.
For a Halo remodel fixture:
Look up into the housing to see if you see 2 wires going from the trim to a plate above the socket.
Remove both wires and the trim will be disconnected.
There will be 4 black spring clamps that will need to be disengaged to remove the can or re=engaged to secure the can.
Push the can up to the ceiling and slide the clips up to clamp the sheetrock. Sometimes you can do it by hand, other times you need a screwdriver.
Reinsert the trim and put the bulb back.
Atlite will require a different scenario.
