Why are my headlights and dashboard flickering?
What's Happening When Your Headlights and Dash Lights Are Flickering? When you couple flickering headlights with flickering dashboard lights, the alternator has more than likely worn out. A worn-out alternator typically needs to be replaced.
Will a bad battery cause lights to flicker?
Remember that your battery is responsible for the electrical components of your car, including the interior and dashboard lights. ... Similar to dimming headlights, these flickering lights are a sure indication of a failing car battery.
How do I stop my headlights from flickering?

Why is my car flickering when I try to start it?

How do you tell if its your battery or your alternator?
If your engine won't turn over or takes far longer than usual, it's time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won't start again later, it's likely a battery problem. If your vehicle immediately stalls, it's probably a bad alternator.
What causes headlights to dim while driving?
Common reasons for this to happen:
Corroded Ground Wire: One of the most common causes of dim headlights is a corroded ground wire. Ground wires connect the bulb circuit to your car's chassis (which serves as the ground itself). ... Bad Alternator: Another very common reason to see dim headlights is a failing alternator.
Why do my headlights flicker when I hit a bump?
This often happens when the car goes over a particularly violent bump. ... Some newer cars use high-intensity discharge (HID) bulbs that require a ballast to regulate the voltage going to the bulbs. A faulty ballast won't provide enough voltage to your headlights, so this can also cause the headlights to flicker.
Can AutoZone check my alternator?
Every AutoZone in the USA will check your alternator, starter, or battery at no charge.
What happens when your alternator goes out while driving?
A bad alternator will result in a discharged (dead) battery and cause a vehicle to not start or run. Alternators are designed to maintain a battery's charge, not to recharge a dead battery. Your alternator's job is to maintain a consistent charge on your battery. Draining your car's battery is not advised.
