LED Headlight Bulb Keeps Blowing Fuse: 6 Problems & Their Fixes

LED Headlight Bulb Keeps Blowing Fuse Problems and Fixes

Why does the fuse on my LED headlight bulb keep blowing frequently? Below are some of the causes of this and what you may do to prevent it.

Recently, one specific item has become the talk of the town due to its wide-ranging uses, which include torches, streetlights, and even headlights. Yes, you are correct; they are LED headlights. Ideally, purchasing high-quality bulbs is the best course of action. Headlight bulb blowing is such a communal problem these days. Several factors contribute to the blowing.

First off, because their inner components are not strong enough, cheaper bulbs may be readily shattered by any amount of electricity. To prevent producing more heat than necessary, making sure the connection is tight is also advisable.

What are the LED Headlights?

Light-emitting diode headlights are known as LED headlights. They transport the photons that produce light via semiconductors, which emit energy. Some of these lamps need extra fans or heat sinks to regulate the temperature since they may get quite hot.

Benefits of LED Headlights?

But have you ever wondered what draws the automobile industry to these lights and what makes them such an excellent choice for headlights? The great brightness output and efficiency of LED car lights are undoubtedly the key factors in the solution. For the benefit of the environment, you can choose to use LED headlights on your automobile as an eco-friendly choice.

Enhanced Lighting

They have a significantly crisper, brighter illumination output.

Improve Your Visibility

The high brightness output of LED lights gives a far wider field of sight, increasing driving safety as a result. It is one of the car exterior accessories providing a white light that is brighter and more piercing, improving vision and allowing for clearer driving situations.

With the LED lights, a driver can also have more time to respond to changing weather conditions and feel confident and safe while driving.

Long-lasting

The typical lifespan of a halogen headlamp is just 1,000 hours or 1/5th of that of an LED headlight.

Greater Lumen

When compared to halogen headlights, LED headlights emit more lumen, making them a more powerful illumination alternative.

Minimal maintenance

As these lights produce far less heat, they require no maintenance. It can survive at least 22 years with a steady 50% usage.

Easy to Install

Likesome of car interior accessories, installing the LED headlights is quite simple. To do the work, you don’t need to be a technical expert or mechanic or possess any specific technical skills.

You can install LED headlights in 30 to 60 minutes with a few basic tools and clear instructions. Each LED kit includes a booklet with instructions.

No need to change the bulb

One of its main advantages is that the LED light requires less frequent bulb replacement. You will save the hassle and trouble of routinely changing the car’s headlights.

For automobile owners, this is a tremendously convenient and time-saving choice. Even you may reduce some extra costs via the method.

Reduces Fuel Use

LED lights give forth a brighter, higher-quality light while using less energy. This is a special characteristic that is mostly lacking in other lighting systems. It improves fuel economy as a result, which might help you save money.

What are the differences between LED and HID Lights?

The following are some of the main characteristics and differences between each:

Brightness:

While HID lights may only have 8,000 lumens of brightness, LED lights may reach brightness levels of 9,000 to 10,000 lumens. However, both are more vibrant than conventional halogen lights.

Technology:

HID lights require gas (typically xenon), but LED lights use electricity.

Energy consumption:

Both consume more energy than halogen. However, LEDs are more energy efficient.

Lifespan:

HID lights have a lifespan of about 15,000 hours, but LED lights may last up to 45,000 hours.

Bulb design:

LED lights frequently have heat sinks, locking tabs, and diode-equipped bulbs. HID headlights may include electrodes, electrode chambers, outer bulbs, and locking tabs.

Price:

HID headlights are normally less expensive than LED headlights.

Startup time:

In contrast to LED lights, HID heating filaments may take a while to ignite.

Colors:

HID and LED lights each provide a variety of color options.

Range:

The typical range of both HID and LED lights is 300 meters (about 985 feet).

Consider using halogen or HID lights if you commute more throughout the day. You may also go for HID if you’re seeking a temporary fix. Given their brightness, ease of starting, and lifespan, LEDs are our recommendation for folks who drive at night frequently.

Why LED Headlight Bulb keeps Blowing the Fuse and How to Fix the Problems?

There is a circuit control system, not just in a car but throughout the entire electrical system! Circuit breakers and fuses are the circuits’ protection. Knowing why a fuse has blown is critical to preventing a car’s lights from blowing. The breaker is most likely to trip and become damaged if this occurs. Most of the time, the fuse pops!

Loose Wires

When the circuit isn’t as complete as it should be, there’s a good likelihood that too much electricity will produce more of an “arc,” which means the energy won’t flow smoothly. The fitting will blow because of the tremendous heat it produces.

When the spring’s internal connection is loose, electricity will “arc” around the contact, which eventually causes an excessive amount of heat to be released.

Problematic Voltage Regulator

Regulators, also known as voltage stabilizers, are equipment either connected to an alternator or installed separately. The electrical apparatus holds or controls the maximum voltage limit for the headlight bulbs not to blow a fuse. This is so that all the components of the system can use it.

A malfunctioning regulator will cause voltage spikes, making the electrical system unstable, which in turn leads to a blown headlight fuse. Check your regulator if it’s intermittently showing voltage spikes.

Changing your alternator belt can help you prevent power surges if your voltage regulator is functioning properly. In addition to installing resistors in the beam circuits, you can also use transistors. Before replacing the belt, however, you should evaluate the regulator.

Exercise and Immoderate Vibrations

Halogen lights do not respond well to excessive or inappropriate filament vibrations. An effortless way to check for vibration is to ensure the LED bulb’s spring is in place. If the chip moves, the intense vibrations cause a fuse to blow.

Additionally, make sure the headlamp is firmly fastened to the primary apparatus. It’s important to remember that any item that might cause vibrations needs to be examined to ensure the headlight bulb is working correctly; otherwise, it will fuse.

Cheap and Poor Quality of Bulbs

Low-quality bulbs can be particularly prone to failure under any of the less-than-ideal circumstances that could ordinarily cause a bulb to blow. Because cheaper bulbs often have weaker filaments, when a filament bulb blows, it breaks at its weakest place.

Condensation in the Headlights

The headlight glass must always be dry and clear of debris. Moisture will gradually build up on the light bulb’s surface with moisture, which will lead to blowing.

Holding and Touching the Bulb at the Time of Installation

Halogen bulbs are unsuitable for headlights because of uneven heating. To work well and last a long time, these bulbs must be heated evenly throughout their surface within a few seconds.

Fitting the bulb without touching its surface is not easy. In addition, your hands are already greasy when you get to the fitting stage. Even though this is extremely rare, you can permanently damage the bulb by leaving dirt on the glass.

Due to this, we recommend wearing latex gloves when installing the metal base.

Frequently Ask Questions

– Why do my Headlights Keep blowing the Fuse?

There might be a variety of reasons why headlights keep blowing fuses. However, the main causes include poor-quality lights, problematic voltage regulators, frayed wires, excessive vibrations, and exercise.

– Do LED Headlights need a Fuse?

While not all LED lights require a fuse, the headlights must have at least a 2-amp fuse to function. A typical headlight uses a beam that is at least 55 watts in power. Therefore, you’re ready to go if you connect your LED headlights to a 10A fuse.

– Can LED Lights Cause Short Circuits?

If there is excessive moisture inside the bulbs or if LED lights are combined with CFL lights, short circuits might occur. An insufficient power supply for the LED lights might potentially result in short circuits.

– Can LED Bulb Fuse?

Even though it’s rare, LED bulbs can still fuse for various reasons. An excessive amount of electrical energy might explode the bulb. If the chip inside the bulb fails to convert the potential draw to a direct voltage, the bulb may explode under excessive voltage conditions.
