it cold have lost ground or made a poor connection in headlight. one wire will be for low beam the other for high beam. under your seat there shold be a few circuit breakers that act like fuses. whe the one melted the circuit breaker kicked off and stopped power from going to headlight. with a test light turn headlight on and see if yellow or white wire is live. You wil have to make sure you have good ground when you replace this. there are headlight replacement pieces at most auto stores-like the plug that goes into the back of theheadlight. when you install this make sure that you have it wired correctly and don't twist wires, solder if possible with shrink tubing covering to protect it.

looking at the wattage on the bulb it is 100/80. Looking in my harley manual the headlamp amperage draw is 4.7/4.3 which converted is 56.4/51.59 watts. does this mean the bulb that was in the headlight was too high of a wattage and it overheated?
