Check your grounds. You can test the power for the headlights at the sockets by removing the bulb and test for power on the brass bulb contact. Just make sure no to touch the socket can with the test light. Make sure the other end of test light is touching a known good ground (no paint or anything in the way). If you have power there the the problem is a bad ground or bad bulb. You can verify a bad bulb by using the socket can as the ground. If it lights then it's a bad or incorrect bulb.

If no power then repeat the test with the terminals on the dimmer switch. And see if there is any power there. If there is and on at least one of the other terminals, then the problem is in the wiring between there and the headlight sockets. If no power there, even on all the headlight positions, then the power is either at the switch of thr wiring between the two.

The same concept at the horns.

Start at the destination and work back towards the soruce. My money is on bad grounds.
