Dash temp light with gauge?

[Stocker]

Is the "Temp" warning light used if there's a factory temp gauge? I'm replacing HVAC ducts and the old dash pad, so my gauge panel is out for the first time. While checking all the light bulbs, I noticed one is missing -- the one for the "Temp" warning light. Factory temp gauge is in place and working, just wondering if I should replace the missing bulb, maybe have a gauge plus an idiot light. Does it even work like that? Thanks, guys.
