Welcome to the site Keezo. If you have proper power to the connection in the headlight plugs (sockets) then it points towards a bad earth connection. However if you are measuring that power with a volt meter bear in mind you can get a 12volt reading even with a high resistance in the feed circuit, such as a poor contact in a switch or connector as others have suggested. i.e it can pass a few milliamperes to give a voltage reading but not enough amps to light the main bulbs. To check the earth connection before pulling switches apart you could try placing a bulb in the socket and run a separate wire from the bulb body to some bare metal on the frame and if it then lights up the problem is with the earth connection. Possible a Brocken earth wire.
Be interesting to know if the tail light was coming on, although I’m not sure what that would indicate without studying the wiring diagram. Likewise the instrument lights working or not might help to narrow the problem source down. There is always an answer to these things, just a matter of finding it!
