Be careful when removing the small plastic cover on the newer models (2023->). The cover has two additional plastic "hooks" on the inside (top/bottom). The two additional hooks will likely break when you pull or reseat the cover. Those hooks are just very fragile. It's properly advisable to replace the cover. Also may want to push the plastic brackets (under the screws) a little upwards/downwards before tightening the screws. This will ensure that the taillight is more firmly held in place so that it does not rattle in its socket. It tends to be a little lose as it is only fixed by the two screws at the end of the taillight.
