At first it seemed to fit well but the handle holding the bulb is too long and heavy making it too easy to fall out of the socket. After a bit of frustration, I realized that the "leg" attached to the fork should be inserted into the faceplate. Loosen the screw on the bezel, install the light and screw the light back on, and it's very strong.
