Bump here but I'm running into the same problem here and can't find the solution that he found.. installed tst flush mounts a few weeks ago and could have sworn that both my front and my rear running lights were working but just tonight I noticed that my rear running lights WEREN'T working and my front tst flush mounts WERE running. Activating the turn signal will cause both front and back signals to blink like new, it's just the running lights in the rear that don't work. Anyone know what's wrong?
