You need to install the bulb into the socket, position the vanity mirror lamp lens to the sunshade, align the lens tabs into the housing slots and insert the upper edge of the lens first, insert a small flat-bladed tool at the lower edge of the vanity mirror lamp lens then press up to fully install the lens and close the lamp cover door and raise the sunshade.

You need to lower the sunshade and raise the mirror and lamp cover door, insert a small flat-bladed tool at the lower edge of the lamp lens towards the middle of the sunshade, lift the lens enough to clear the plastic housing, and remove the vanity mirror lamp lens from the sunshade and the bulb from the socket.
