Warning Lights on Dash

[sjh]

w124 - '90 300D - turbo.

I'm driving to work. All is well. I park and go inside. I come out 3 hours later and turn the key. None of my dash warning lights come on except the SRS and ABS on the right side. None of the lights on the left side will light.

As best I can tell the warning lights still function, they just don't display a self-check when the key is first turned on.

Any advice?
