Car Headlight Flickering: Causes and Solutions

“Excuse me, driver, please turn on your headlights when it’s dark!”. This seemingly simple reminder has more to it than we think, especially when your car experiences “car headlight flickering”. As an expert at Hanoi Trucks, I’ve encountered numerous customers who came to us feeling confused and worried because their beloved cars suddenly developed this headlight “disease”.

Today, let’s join me, Nguyen Van A, chief technician at Hyundai Truong Chinh truck dealership in Thanh Xuan district, Hanoi, to “diagnose” this common yet annoying problem.

What is Car Headlight Flickering?

Simply put, car headlight flickering is a phenomenon where your car’s headlights flash repeatedly or don’t shine evenly and steadily. This not only causes difficulties for you when driving at night or in low-light conditions but also poses a safety risk to yourself and other road users.

Causes of Car Headlight Flickering

So, what’s the “culprit” behind car headlight flickering? Based on my years of experience, I’ve noticed some common causes:

1. Faulty Headlight Bulb

This is the most common cause. Prolonged use, poor quality bulbs, or exposure to water can lead to burnt bulbs or broken filaments, causing flickering.

2. Loose Wiring or Poor Connection

During operation, vibrations from the car can cause the wire connectors in the headlight assembly to become loose, resulting in poor contact and unstable headlight operation.

3. Problems with the Cigarette Lighter or Fuse

The cigarette lighter or fuse is responsible for protecting the headlight circuit. If they have problems such as looseness or damage, it will also affect the operation of the headlights.

4. Damage to Other Components in the Headlight System

In addition to the common causes above, headlight flickering can also stem from other components such as the light switch or ballast (in the case of cars using xenon lights).
