Hello and welcome to the forum. lf your headlight is not working and you've checked that it's getting power, it's probably time to knock on the KTM dealer's door and ask how much a new one costs.
Be sure it's the unit. Check if there is good grounding and voltage before replacing it. Mine had had a lot of problems till I discovered damage on wirings close to the turning point of the handlebar.
I had mine broken all of a sudden. Looks like its an Thermal Relay, which turns on when sufficient current is being drawn. By the looks of this, its broken. get a new one, it costs Rs400(6USD) in india
