It shouldn't have been too difficult – I'd done the other one a few months ago, so I even knew what I was getting into. But one stripped plastic screw, one totally stuck headlamp assembly (it had a warped edge) and about two hours later, having two working headlights feels like a real victory. Special thanks to the neighbor chick who told me I looked "like a badass" covered in grease, to @rick.niley for moral support, and to another neighbor I met (also named Nick) who tried to help me. He didn't get the headlamp assembly unstuck, but his willingness to try gave me some extra wear-withal. Anyway, blah blah blah, behold my power and fear me.
