chevy had the reverse lights installed in the bumper completely inaccessible unless you took off the bumper. Couldn't come down from the tail lights and couldn't come up from under the car. I never realized it before. Idiots, why would you design something like that?!? Went ahead and switched out the bulbs while tapping the wire for the camera trigger on the radio because I knew as soon as I got it back together, one of the reverse lights would go out.
