WHAT IS THE RED LIGHT

[b]JUST CURIOUS WHAT THE RED LIGHT IS BEHIND THE STEERING WHEEL.IS IT A WARNING LIGHT?
ITS ON A 68 SUBURBAN

That red light is in the battery charging circuit If I remember right If it's on the battery isn't bring charged I've worked on these tractors for Sears for 40 years so many years so many models it's gotten hard to remember. But the red light should go on when you turn the key and go out when she starts.
