My taillight harness is brand new
There was a thread somewhere recently and his issue turned out to be the inner socket disc in his new harness had been installed 180 degrees off.
I saw that thread and I checked that. My bulbs are both operating correctly. Each side is on the correct element for run and brake. I also double checked the grounds and they are fine. Adding a second ground doesn't make any difference and the voltage drop to ground is very small. I'm pretty sure it is a problem with the lens.
