I think the lense is bonded to the plastic light body somehow even though there's a steel clip at each end of the light unit that look like they're holding the glass to the light body. To remove the whole light, remove indicators and grille, unscrew from the front, three hex screws at the corners of the lamp with a 10mm socket, then from inside unscrew the self tapper at the top left corner only (looking in)etc etc. hope thats some help.
