Random dim lights

I suspect a bad ground up front by the grille and core support. Try running some temporary extra ground wires to see if that cures the problem. Get/make a set with alligator clips and make sure you have a good connection on each end.....socket to bare body ground or all the way to the negative post on the battery. Dash lights were never blinding on those dashes. I like using LED replacements that have a higher lumens spec. than stock incandescents. You can even change the color if so inclined.
