Left front main beam lightnot working

Hi to all... the front light(left) headlight is not working. The only lights that are functioning on the front left are the fog and parking lights.
At first i thought it was just a bulb (HID) but why would the main beam not work? I switch the right (working) bulb to the left and is not working. Any ideas?

When you switched the bulb, that side still not working right? Did you power cycle the vehicle to reset the SAM? If it still doesn't work, might be a bad ballast. Probably covered under warranty if yours is still active.
