What Are the Common Signs of a Broken Headlight?

Recognizing the symptoms of a broken headlight is crucial for maintaining vehicle safety. Here are some typical signs:

• Dim or Flickering Lights: If your headlight appears dim or flickers, it might indicate a failing bulb or electrical issue.

1. Visual Inspection: Check for visible damage like cracks or moisture inside the headlight.
2. Turn On the Headlights: Observe if both headlights illuminate properly.

What Causes Headlight Failure?

Understanding the causes of headlight failure can help in preventing it. Common causes include:

• Burned-Out Bulb: Over time, bulbs naturally burn out and need replacement.
