L48 glow plug light

[mfl_jr]

Howdy, I am noticing that the glow plug light on the dash of my L48 is staying illuminated for a good while lately. Like 20-30 minutes after I start the tractor. I don't recall this being a thing "before", but I'm not positive about it and the weather *is* getting cooler... Does anyone know if this is normal behavior or do I have a problem here that I need to take a look at? Thanks!

ok, so I don't see a way to delete my post. I'm probably just not seeing it, but anyway I believe I found the answer here: https://www.tractorbynet.com/forums/threads/l48-glow-plug.349460/
