The headlights are not fused. The headlight switch has a built in circuit breaker.

Possibly the headlight relay underhood or headlight module behind glovebox

20:1 is what honda states
I just saw this in a Goldwing Repair book at the dealer. First look at the headlight adjustment knob inside the faring. Twist it until you see a retaining screw. Remove the screw and then remove the knob. There should be a nut around the main headlight shaft that you can remove, which will then allow you to slide the entire headlight assembly out through the front of the fairing. Once the whole assembly is out, remove the retaining ring and disassemble the light housing. Reverse the process to reassemble.Good luck!
