I have 2 different combo fuel/temp gauges and I don't what the 2 come from originally?
This first one looks older and has a light that can illuminate the far end of the temp red zone, never seen one with a warning light in it?

This second one looks newer and more what I expected, no warning light in the temp gauge.

I expect the first one is from a 911 but I don't recall any of the 911s having a warning light in the red zone of the temp gauge.
