Welcome.
Now dash lights come from h/l switch which btw has internal circuit breaker that resets itself. I'd either replace h/l switch (assuming all plugs at dash are good and connected as well as ground wire for cluster and bulbs ok) or take a look at h/l switch in particuliar the white ceramic disk which controls dash and interior brightness. Sometimes contact on switch to disk get dirty and corroded. Try cleaning with emery paper or just replace switch.
