Any applicable fuses, did you use a voltage tester to check for voltage at the fuse circuit?

All I can do is track the voltage circuit and check ground. Did you check for voltage and ground at the headlamp assembly?

At the headlamp switch, do you have voltage at the red wire with orange tracer? Then, with headlamp switch on, the tan wire with black tracer should be hot, is it?

Check the wiring at the dimmer switch. Tan wire with black tracer hot with the headlamp switch on. Violet wire with white tracer, also hot, carries voltage to headlamps.

If the voltage circuits are all ok, check the ground at the headlamp connector, black wire. One way to check ground, is to use a testlite connected to battery voltage, touch to black wire terminal, with connector loose, if the lite comes on, the ground is good.

What is the actual voltage reading at the lamp? If it shows system voltage at the lamp and you have good ground, I don't know?

The top wires in the head lamp diagram are voltage, comes from the dimmer switch. It could an issue with wiring circuit from dimmer. I've given you all the diagrams.
