New dash lights stole my energy.

Failures like this are often connections at connectors

What year/ model? If you have a seat belt interlock, that can complicate things

It's helpful to know how the dash lamp circuit works. The headlight switch receives power from TWO separate sources

Headlights ONLY power comes directly to the switch from the splice in the harness, in the black ammeter wire. There's a breaker in the light switch for the headlights

Tail/ park and dash get power from the tail fuse. So make sure the tail lights work.

Then, dash light power goes through the dash dimmer switch (wiggle the heck out of it!!!) and FROM the dash dimmer, lamp power goes TO the small instrument fuse, and one end of your fuse panel.

So, with lights in either head or park, and the dimmer control all the way to "bright" see if you have the same voltage on both ends of the instrument fuse.

If the radio, heater bezel, or shift selector lamps light, but none in the cluster, then you have a problem most likely either a ground at the cluster, or at the cluster harness connector.

If one or two cluster lamps work, then check the sockets and connections between the two boards (on many years) which jumpers dash lamp power between the two boards.
