Why are my high beam headlights not working?

In the case of high-intensity discharge (HID) headlights, or Xenon headlights, there’s an additional component.

How does a headlight switch turn on a high beam?

In the same way that your headlight switch activates a relay to provide power to the headlights, operating your high beam control will generally activate a relay to turn on the high beams. In the case of dual filament headlight capsules, this literally sends power to the high beam filament.

The connections to the wires can get loose or some rodents can chew them. In that case, high beams will work if their wires are fine. So, these are the most probable reasons for disrupting the functions of headlights without affecting the high beam lights.
