So, tail on bottom on left side and top on right side. had to mod the bracket to be able to flip the right side 180 degrees.

So, both tail lights wired to same circuit...one is brighter than the other. I think this is a grounding issue through all the new paint...so going to add a dedicated ground wire from tail light assembly stud to frame.

I tested both tail lights before installing and knew which wire was tail and which was stop. Brightest is always stop. Grounding issue seems the most obvious because when lights wired directly to small 12v battery, the brightness is the same.

Yeah, sounds like a ground. Although it's painful, the best ground is achieved by grinding any paint or surface rust off before you attach your ground. Ask me how I learned that lesson dang
