Strange new dash light came on (1 Viewer)

I was doing some exploring last weekend and at one point we hit some nasty washboards. Not a big deal, but this new light came on and I don't know what to do about it...

Seriously though the D light hasn't worked since I've owned the truck, and now it is working most of the time. Wtf?

Bad bulb connection. Super common "fix" is to hit the dash above the cluster if the light isn't on.

I think if mine came back on, I would hit the dash until went off. That thing is too bright and unnecessary.
