HEADLIGHT FLICKERING: A FEW POSSIBLE CAUSES

Flickering headlights aren’t only an annoyance; they may also be deadly on the road! With this useful advice, you’ll learn what causes flickering headlights and how to fix them.

1. DYING BATTERY

A dead battery is one of the most prevalent reasons of headlamp flickering. The battery is required for the correct operation of your headlights. Flickering or fading headlights may be the consequence of a failed battery. In this case, you should visit your nearest Tires Plus for a free battery inspection. If your headlights are flickering because of a dead battery, it’s time to get a new one.

Typically, a car battery lasts three to five years. Short excursions, keeping your car parked for lengthy periods of time, driving a vehicle with various aftermarket electrical devices, or living in an extremely hot or very cold region can all reduce the battery’s lifespan.

2.  FAILING ALTERNATOR

The electrical output of your automobile is impacted when the alternator starts to fail. Because headlights rely on electricity from the vehicle’s battery, this might result in flickering, dimming, or inoperative headlights. The vehicle’s electrical system will quickly deplete the battery if the alternator is unable to charge it. Whether you find yourself in this situation, get your alternator checked by a professional to see if it needs to be repaired or replaced. Keep in mind that if your car’s battery light comes on, it typically means your alternator is malfunctioning or the battery isn’t being charged properly.

3. LAMPS OR WORN-OUT BULBS

Flickering headlights might occur if the bulbs or lamps in your headlights are outdated or broken. Fortunately, there is a straightforward cure for this. Bring your car to a Tires Plus near you, and one of our specialists will repair any burned-out or broken bulbs or lights.

4. FUSES OR LOOSE CONNECTION

It’s possible that the headlights are flickering because of a loose connection or because the fuse isn’t correctly positioned. When driving on a rough surface, such as a gravel road, you may notice this issue more. Because loose connections and blown fuses can be difficult to detect, it’s best to bring your car to your local Tires Plus to have your electrical system fully examined.

5. INAPPROPRIATE WIRING

Physical damage to headlamp components might cause a headlight to start flashing. The interior of the connector may begin to melt, resulting in a weak bulb connection. The wire may start to pull out the back of the connector in rare situations, resulting in a weak connection.

It’s possible that replacing the damaged components will solve the problem. Because doing so necessitates the disconnection of electrical components, a competent technician’s examination might pave the way.

6. FAULT IN THE HEADLAMP SWITCH

Your car’s electrical system and computer system may not be “talking,” resulting in flickering headlights. This issue can be caused by a faulty headlight switch in rare circumstances. You might be able to fix this by installing a new headlight switch. It may also necessitate a more thorough examination of your car’s computer or electrical system, which includes the fuses, relays, switches, battery, and alternator.
