After the quick test drive last night, I discovered that one of my backup lights was out. Since I was fiddling with the taillights, I figured I may have fucked it up, but just to be easy, I checked the bulb this morning. Sure enough, it was burned out. A replacement was had from the neighborhood NAPA, and a few minutes later, was in place. I still have to route the power wire and attach the ground, but I am suddenly overwhelmed with sleepies and will likely nap first.
