The right and left outer corners (lower grille) of the bumper have little tabs that slide into grooves in the bumper cover. These grille covers connect at the lower grille section of the bumper. Caution! There are little garnish covers that cover where they meet. Pull these snap on garnish covers off first, then start to pull the grilles away from the cover (this will take some effort). Once you remove the grille(s) you can get to the screws on the metal trim bezel of the lamp. Remove the screws and the metal bezel will slide out of the way so you can pull the glass globe foward so you can change bulb from the back side. I hope this helps.
