Thought I would share what I found to be an easy and quick fix for tail lights gone bad. So I had tested all the bulb sockets and they all worked if I gave them power and a ground. Next I tested the circuit board for each socket location by activating the function of that specific socket. What I found was some sockets either didn't have the ground or the positive not working properly.

I purchased two circuit boards off ebay for about $20 each including shipping. Today after about 10 minutes of very easy installation all my tail lights are functioning properly. I had thought about buying an entire lens kit but no need.
