Subro

Hi, I have a 2011 Impreza 1.5 hatchback imported from Japan. The left rear reverse light clear lens (on the hatchback door, next to the brake and indicator lens assembly) is collecting water. There are 2 screw-in metal bolt heads visible straight away which I removed. I then raised the door, removed the plastic trim and disconnected the bulb assembly. There does not appear to be any other tabs or screws holding the lens in place. However, it is very difficult to remove the lens. I tried pressing out the left side of the lens so that it came off the length of the threaded bolt and used a screwdriver to gently push out the right side of the lens, but only succeeded in breaking off a bit of the plastic! Any advice on how to do it right? Thanks.
