A weak battery may not give out enough power for your headlights, causing them to go dim or flicker. Of course, in that case, you’ll notice other issues before you notice flickering headlights.
Can a bad alternator cause headlights to flicker?
Even if you’ve never seen this happen, it does happen. An issue with the alternator (or the voltage regulator, which is often located inside the alternator) can cause the headlights to flicker. Such charging system problems may lead to inconsistent current output, which can cause your headlights to flicker.

Why does my HID light keep going out?
Any signs of condensation inside the headlight housing may indicate that water is leaking into the housing. Water and electricity don't mix and any condensation may cause a short circuit leading to failure. Also, any condensation coming in contact with a hot bulb may cause the bulb to break.
Can a bad ground cause headlights to flicker?

2,000 to 3,000 hoursAn HID bulb should last anywhere from 2,000 to 3,000 hours. That's up to six times longer than the shortest-lived halogen bulbs. With an HID bulb, you should get several years' worth of use before the bulb needs to be replaced.Jul 11, 2019
What is better HID or LED?
They have an average lifespan of more than 20,000 hours, which means they need to be replaced far less often than HID headlights, which have an average lifespan of up to 5,000 hours. LED headlights are also more durable. If you're looking for long-lasting, high-quality headlights, we suggest ALLA Lighting LED bulbs.Oct 29, 2021
Do HID lights fade over time?
The short answer is yes, they do. Both LED and Xenon HIDs will lose up to 70% of their original light output gradually over time. Halogen bulbs, on the other hand, hardly fade over time. They simply stop working when they've run their course.
Do HID bulbs burn out?
While a halogen bulb is the most likely to simply burn out and require a sudden replacement, with HID bulbs you may notice that their power begins to fade over time. HID bulbs lose approximately 70% of their power over their lifespan, meaning they will not provide the same quality of life as they did before.Jun 15, 2020
Why are my lights flickering?
5. Your bulbs are dim, off-colored, and flickering. This typically means that the bulb is not getting a consistent voltage. If it's just one bulb, it's likely the ballast or one of the connections in the wiring.
Why do my bulbs flicker?
Your bulbs flicker. Flickering HIDs is a very common issue. It usually means that the bulbs are not getting consistently high, constant voltage. This can be a problem with the ballast, the connections, the wiring, or the battery. If only one bulb flickers, it may also be the bulb or ballast for that side.
Why replace a faulty headlight kit?
We strongly recommend replacing a faulty kit, because a faulty kit can cause excess battery drain, a shock hazard, and can even start a fire . 2. Your ballast is bad. Each HID bulb needs a ballast to power it. If one of your headlights works fine and the other does not, it's a possibility that the ballast is faulty.
How do HIDs work?
HIDs are High-Intensity Discharge lamps, usually a Xenon bulb, in a projector housing. Traditional halogens and other incandescent light bulbs use a filament, which glows hot enough to emit light when electricity is passed through it.
Why do my lights turn off and on?
Your bulbs light inconsistently. If it takes effort, toggling between low and high beams, or turning your lights on and off to get them to light, you may have an issue with your battery, ground, wiring harness, switch, or another part of your system.
Why is the halogen bulb dead?
Much of the design of a halogen bulb is spent on isolating the atmosphere inside the bulb to protect the filament from anything that could damage it because once the filament breaks, the bulb is dead . The biggest issue with halogens is that 80% of the power sent through it is emitted as heat, not light.
What are the problems with HIDs?
One of the most common issues with HID systems is improper installation. The bulb, the ballast, and the wiring all need to be firmly and tightly installed, and hidden from moisture. HIDs also need to be grounded properly to function correctly, and improper grounding is a common installation error.
Why are my headlights flickering?
What Causes Flickering Headlights? Flickering headlights are caused by either a faulty bulb or a problem within the headlight circuit. Generally, flickering headlights are caused by either a faulty bulb or a problem within the headlight circuit.
Why do my halogen headlights flicker?
But halogen headlights don’t often flicker that way – it’s possible, though, because if the filament is in two pieces, the ends of the broken filament can touch intermittently, which will cause a flicker, but that’s the exception rather than the rule. A failing bulb can cause your headlights to flicker.
Why do my headlights go out at night?
So, for that reason, headlights on older vehicles have a self-resetting circuit breaker built into the headlight switch to prevent a total sudden loss of the headlights if possible.
How long do halogen bulbs last?
That being said, it’s not unusual for halogen bulbs to literally last over 100,000 miles, so it’s not a foregone conclusion that you’ll ever see a flickering light or ever even have to replace one.
How to diagnose a headlight flickering?
You can diagnose your headlights by doing a visual inspection. The first step is to perform a visual inspection. Look for issues, such as:
How many fuses does a headlight bulb have?
Newer vehicles may have a circuit breaker external to the switch, but usually they have a separate fuse for each filament of each headlight bulb, i.e., four filaments (2 bright, 2 dim), and four fuses, one for each filament. That way if a short occurs in a wire leading to one of the filaments, the rest of the filaments will still work.
Why are my headlights brighter than normal?
If your headlights appear brighter than normal, the problem may be related to a high battery voltage. If only ONE of the headlights is brighter than normal, that headlight is beginning to fail. Check the charging system voltage and make sure that it is less than 15.5 volts, which is the standard for most vehicles.
1. Dying Battery
One of the most common causes of headlight flickering is a dying battery. Your headlights rely on power from the battery to function properly. If the battery is failing, flickering, or dimming headlights may be the result. In this situation, you’ll want to get a free battery inspection from your local Tires Plus.
2. Failing Alternator
When the alternator starts to give out, your car’s electrical output is affected. This could result in flickering, dimming, or inoperative headlights, as the headlights depend on power from the vehicle's battery. When the alternator is unable to charge the battery, the vehicle's electrical system will quickly drain the battery.
Schedule an Appointment
Keep in mind that when your car’s battery light illuminates, it usually indicates that your alternator is failing or there is an issue charging the battery.
3. Worn-Out Bulbs or Lamps
If the bulbs or lamps of your headlights are old or damaged, it can cause the headlights to flicker. Fortunately, this can be a relatively quick fix. Bring your vehicle into your local Tires Plus, and one of our technicians can replace the old or damaged bulbs or lamps.
4. Loose Connection or Fuses
When the headlights flicker, it could mean that there is a loose connection or the fuse may not be properly seated. You may especially notice this problem when you’re driving on a rough surface, such as a gravel road.
5. Bad Wiring
Sometimes, a headlight may start flickering due to physical damage to headlight components. The inside of the connector may start to melt, causing a poor connection to the bulb. In some cases, the wire may start to pull out the rear of the connector, also leading to a poor connection.
6. Faulty Headlamp Switch
If the electrical system and the computer system of your car aren’t “talking,” you may end up with flickering headlights. A failing headlamp switch, in some cases, may cause this condition. You might be able to resolve this by having a new headlamp switch installed.
