How To Tell The Signs Of Faulty Subaru Headlights

Headlights are an essential part of your Subaru's lighting system, providing the necessary illumination for nighttime driving and inclement weather conditions. When they start to malfunction, they can compromise your safety on the road. At Empire Subaru, we understand how crucial it is to have reliable headlights. In this article, we’ll walk you through the common signs of faulty Subaru headlights and explain how to address them.

Dimming or Flickering Lights

One of the most common signs of faulty headlights is dimming or flickering. If your headlights lose brightness intermittently or seem dimmer than usual, it could indicate several issues:

• Burned-out Bulbs: Headlight bulbs naturally wear out over time. If one bulb dims or flickers, it’s likely near the end of its life and should be replaced.
• Electrical Problems: A malfunctioning alternator or wiring issues could cause your headlights to flicker. This can be a sign that your Subaru's electrical system needs attention.
• Weak Battery: A dying battery can cause fluctuating power to your headlights, leading to inconsistent brightness. If your battery is nearing the end of its lifespan, it might be time for a replacement.

One Headlight Is Not Working

If one of your headlights has completely stopped working while the other one is still functioning, it’s often an easy fix. However, there are a few potential reasons for this issue:

• Burned-out Bulb: The most common cause is simply a burned-out bulb. If only one headlight is out, it may be time to replace the bulb.
• Wiring or Fuse Issues: If replacing the bulb doesn’t resolve the problem, a blown fuse or damaged wiring may be at fault. Inspect the wiring and fuses connected to the headlight for any visible signs of damage.

Cloudy or Yellowed Headlights

Over time, Subaru headlights can become cloudy or yellowed, especially in older models. This can occur due to the buildup of dirt, oxidation, or wear and tear on the plastic lens. Cloudy headlights can reduce your visibility and make it more difficult for other drivers to see you.

• Cleaning and Polishing: In some cases, cleaning and polishing the lens can restore clarity and improve the functionality of your headlights.
• Replacement: If the lens is severely damaged or the cleaning method doesn’t work, it may be necessary to replace the headlight lens or the entire headlight assembly.

Misaligned Headlights

Misaligned headlights can cause your Subaru’s lights to point in the wrong direction, reducing your visibility on the road and potentially blinding other drivers. If your headlights seem to be pointing too high, low, or to one side, they might be out of alignment.

• Adjustments: Most Subaru models allow for manual or automatic headlight adjustments. If the issue persists, a mechanic may need to realign the headlights for optimal performance.
