Why are the high beams on my Subaru not working?
If the high beam fuse has blown, it’ll need to be replaced and the circuit will need to be inspected for problems. Or, it could be a bad relay. If the headlight relay has failed, it may not respond when you attempt to switch the high beams on.
Why are the lights on my high beams not working?
Improperly installed headlamp bulbs can wear out prematurely. If the bulbs are in good shape, it may be necessary to look at all the electrical components that make your lights work — including the high beam switch. Even the switch you physically turn to activate your high beams can go bad and keep you from being able to turn on your brights.
What makes a car have a high beam?
Most cars on the road today have manual high beams that you activate yourself — but more and more modern cars are coming with automatic high beam technology. Using advanced sensors, the car monitors the level of ambient light and detects oncoming traffic.
Do you need high beams or low beams?
Low beams are the bare minimum, for safety’s sake, but high beams are an absolute must for night driving over 25 mph. For most vehicles, headlights are a basic electrical system, controlled by switches and relays to turn them on and off.
Why does my Subaru have both high and low beams?
This relay then sends the necessary electricity to the lights. The high beams and low beams often use different relays, so it’s possible the low beam relay may be bad while the high beam relay is fine. If the low beam relay is damaged, it may be best to replace it.

How does a high beam light bulb work?
Get familiar with the fuses and relays that control your headlights. The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.
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. To get the xenon and salts to plasma state, the HID generator bumps the voltage up to 30,000 V, then stabilizes around 90 V when the bulb is in operation. If the generator fails, the bulb won’t light.
