Why Subaru Headlights Fail
Subaru headlights can fail for several reasons. Here are some common causes:
1. Burned-Out Bulbs: If the low beams in your Subaru aren’t working, it’s possible that one or both of the low-beam halogen headlight bulbs have burned out. Modern headlight bulbs can be much brighter than they were in the past, so it may be difficult to notice when one bulb burns out. However, if the second bulb burns out, it will become more apparent.
2. Blown Fuse: Another possible cause of Subaru headlight failure is a blown fuse. If everything is fine with the bulbs themselves, it’s worth checking the fuse for the headlights. If you replace the fuse and the headlights start working again, that’s great! However, if the fuse blows again, it could be a sign of deeper electrical issues that need to be addressed.
3. Electrical Issues: In some cases, Subaru headlights may fail due to underlying electrical issues. If the fuse replacement doesn’t solve the problem, it’s possible that there are deeper electrical issues that need to be addressed by a professional.
4. Corroded or Damaged Wiring: Corroded or damaged wiring can also lead to Subaru headlight problems. If the wire connecting the bulb circuit with the car’s chassis is corroded or damaged, it can disrupt the electric flow and result in low output from the bulb.
It’s important to note that these are just some of the common causes of Subaru headlight failure. If you’re experiencing issues with your Subaru headlights, it’s recommended to consult a professional mechanic or contact your local Subaru service department for assistance.

Why do both headlights stop working?
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. High beam headlights don’t work or low beams don’t work. The cause: A burned out bulb, or a problem with the high beam switch or relay.
Why are my headlights malfunctioning?
The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner’s manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
Why do my headlights only last a year?
The Lifespan of Headlights
The natural aging of the bulb along with other factors including your vehicle type and voltage, driving habits, environmental conditions, bulb technology and the performance level of your bulb, all impact the lifespan.
Why are my headlights not working on my Subaru Outback?
Loose or corroded headlight components: Occasionally the electrical connections can become loose or get corroded. The bad connection causes the light to stop working or flicker. Headlights stop working: If both headlights stop working, the issue is most likely due to a bad fuse or a bad electrical connection.
Why are my headlights not working but brights are?
One of the common causes we frequently encounter for the malfunction of low beam headlights, while high beams continue to function, is a faulty headlight relay. In essence, relays serve as electrical switches, and both the low and high beams have their dedicated relays.
How long should a car headlight last?
Headlight Bulb Lifespan
| Bulb Type | Max Brightness | Avg Lifespan |
|---|---|---|
| Halogen Bulbs | 150% | 14 months |
| HID Conversion Bulbs | 450% | 23 months |
| OE Xenon Bulbs | 200% | 20 months |
| LED Bulbs | 300% | 42 months |
What causes headlights to go out often?
A bad bulb: The headlight bulb could be burnt out, loose or the filament inside the bulb could be broken. Electrical issue: There could be a problem with the headlight circuit, such as a loose or corroded electrical connection, a blown fuse, or a damaged wiring harness.
How do I know if my headlight relay is bad?
Your lights off momentarily. Before regaining connection. But the flickering usually gets worse over time. You might also notice that your low and high beam functions stop working properly.
How much does it cost to replace headlights on a Subaru?
Usually, you can expect to pay around $120 – $170 to replace your headlights.
How long do Subaru headlights last?
LED headlights are very common on vehicles these days, and these headlights can last for as long as 30,000. Because LED headlights are designed to last for so long, you might have a connection issue if your LED headlights start to fail sooner than expected.
