Lost some lights

Somewhere today, I lost the functionality of my headlight. I have an HID headlight and two auxiliary lights. Somehow my main headlight stopped working, and one of my extra lights. But God was gracious enough to leave me one to limp around with.

I took it apart and found a broken bulb filament in my left aux light, but I can't figure out my headlight. Fuses seem good. And I have no idea how to tell if an HID bulb is out.

Pictured: my view of Danny's tail with only one aux light, and the view of my bikes innards as seen from my camp flashlight.

Also, doing it all in the dark at a campsite is sorta frustrating.
