Why is my high beam working but not low beam?

Headlight Fuse or Relay If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights. If this relay goes bad, it could allow power to the high beams, but not the low beams.
Why does my headlight only work on high beam?
Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch. Headlights work but seem dim. The cause: Foggy lenses, worn out bulbs, or a charging system issue. The fix: Clean the lenses, replace the bulbs, or repair the charging system.
Why are my low beams out?
Bulbs usually don’t burn out together, but it’s still important to rule that out by checking for power. Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working.
Do low beams and high beams use the same bulb?
On most older vehicles, the answer is yes. It was once the norm to have separate bulbs for your high beams and low beams, but most modern cars have only a single bulb with two filaments on each side of the vehicle that performs the work of both the high beams and the low beams.
Why would high beams not work?

Can a broken headlight switch cause high beams to not work?
We don’t typically see this problem with Subaru models, but a broken headlight switch can be problematic. It may get stuck in position for the high beams or the switch could wear out and simply not turn the headlights on at all. If the switch is bad, replacing it with a new OEM headlight switch is typically the best answer.
What is the difference between low beam and high beam headlights?
One is for the normal low beam headlights and the other for the high beams. Other models might have two separate headlight bulbs. Since the low beams are used the most, they tend to burn our much sooner than the high beams.
Can I drive without headlights in my Subaru?
