So I got my brake light back from Signal Dynamics a couple weeks ago. Their communication with me on this was pretty poor. They never called to say what the issue was or that it was coming back, it just arrived. The invoice said "Repaired, tested" and that was pretty much it. I have verified that it is in working condition again but I am interested to know what caused the failure. As soon as I can get a little garage time I am going to reinstall it. I am trying to be positive here but there is always that feeling in the back of my mind that it will fail again.
