Summary: The design of the piece that holds the bulb and the ring that holds it is not very good I was unable to get the pieces to stay together but I finally settled on flaring out the metal where the retaining ring was supposed to lock on and hammering it flat to hold the socket in place overall it ended up working ok but nowhere near the way it was intended
Worked ok
