It is a Ford chassis. But as mentioned, it looks like the fuse is not broken into "left" and "right" but is just one fuse for "brake, turn, etc".
The left turn signal and hazard is now once again working after I unscrewed it and played around with the wires. I don't like when things are intermittent...
It does look like these lights are made up of dozens of tiny LEDs, and I can see that it looks like on each side there are several of the tiny LEDs that are no longer working. I think I will buy two new light units and replace the ones that I have on there.
