No VSC OFF light when center diff locked

I exercised the 4wd actuator yesterday and noticed that the VSC OFF light didn't come on when the center diff was locked. Isn't it supposed to light up? I have an 04 SR5 w/V8.

The VSC Off does illuminate on my 2008 V8 when I lock my center diff....maybe the bulb burned out?

I don't have any other idea....

That's what I was thinking because it doesn't light up when I start the truck either. Hoping that's all it is.

+1, mine lights up too
most def a burned out bulb

The lamp for the VSC OFF is of course a soldered LED. How would I go about testing just the LED for this?
