Had the same problem with my 95 RRC. I also found the connection at the headlamp bulbs had green oxidation. I had to replace both the connectors and cleaned the bulb contacts.
For some reason when the connections get bad the high beam icon will come on but the headlights will not work.
Glad that you fixed it. Sorry, that I didn’t see your post earlier
