When removing the tail light there are little hooks with holes that are used to hold them in place as shown in the first photo.

The tail should already be loose from the previous step so pull it out slowly by turning it on its side and then pulling forward.

Use the 7 mm socket to unscrew the two bolts securing the brake light housing to the tail light assembly.

The screws in this step are "Rexka 30pcs M4.2-1.41 x 20mm".
