Cluster lamps all go off when turn on headlights?

I bought this vehicle, and it had some problems like oil leaks and some electrical. There was no radio, and I could see splicing done. I really can’t remember if the cluster lamps worked in the first place, I only drove during the daytime. Replaced lamps on cluster, turned on headlights, cluster back light goes off, the permanent hard-wired ones are not affected. I checked fuses all good. I see this problem in all sorts of blogs and not just Hondas.
Hope you can help.
