So I have a blown taillight, I pull the two screws and try to pry the red cover off, and it looks like the sliver plastic of the casing is going to give before the cover comes loose. Like every other piece of plastic on the bike I'm sure there are tabs the service manual isn't bothering to tell me about. I just don't want to f*** up the casing finding, aka breaking, those tabs. So if anyone could direct me I would be most appreciative.
