Help, need a 60 Caddy headlight switch

I tried the classifieds but no luck. Does anybody have a 60 caddy headlight switch fo sale? It might not even be the switch, after a couple minutes with brights, all four lights start to flick on and off. Low beams stay on just fine. I've already replaced the dimmer switch, but no luck. Any ideas?

Thanks

 

I might have a '59...that work for you...???
