Rear blinker does not work need to acc...

My rear turn signal light on the passenger side went out at 41k miles. Ditto emergency flasher for that side. Turn signal click is accelerated on that side as well. Front left turn signal works fine. Suspect a bad bulb. Have bought a replacement but am not sure how to get into the lense assy to change the thing. All my older vehicles either had external screws holding on the lense assy, or twist and turn pull out sockets one could get to from inside the trunk. This seems to have neither.
