There is a plastic bezel on the bottom of the mirror where the lamp is. Grasp the front and rear edges of the bezel and squeeze them inwardly. Pull down on the bezel at the same time. The bezel will come out and the lamp will follow. If you look at the bottom of the mirror, there may still be a little label that tells you how to remove the bulb. I never noticed it until I lookded up from underneath the mirror.
