Hi,
I read through schematics for both the dash lights and the speedo. They both plug into the rear of the instrument panel. What I found is both are powered from different fuses, so I don't see that as a possible issue. Since both fail at the same time, I have a feeling the connection on the rear of the cluster is loose or corroded.
If that checks good, I need you to locate the black wire in the connector and check it for continuity to ground. The ground for this component has a large wire splice. The wire itself could be corroded or loose in that splice.
Here is a link you may find helpful:

When you check both the connection and the ground, while the connector is still attached to the cluster, move the wiring around to see if the lights flicker.
Let me know what you find or if you have other questions.
