LED vs. Halogen Headlights – Which One is More Superior?

Halogen lights were introduced back in 1962, while LED headlights were introduced in 2008. Initially, LED lights were only found on a new cars, and halogen headlights were used for any other vehicle. Today, LED bulbs are used in the headlights of cars by major vehicle brands such as Honda Civic.

Many people consider LEDs as a replacement because of their desirable properties, such as low energy consumption, low power consumption, less heat generation, color temperature, and bright light. One might expect LED bulbs to replace halogen headlight bulbs completely, yet the latter can still be found.

When LED headlights initially came with the more expensive cars, people naturally gravitated towards them and considered replacing their halogen light bulbs. Although blindly following the crowd has rarely produced beneficial results.

Some people believe that the halogen bulb should stay in the past and use a LED headlight instead. So why are halogen headlight bulbs still used in the new vehicle today?

LED vs. halogen headlights, which one is superior? Let’s find out!

What Are Halogen Headlights?

Halogen headlights are very common in today’s automobile industry, and they are easier and cheaper to manufacture. Like incandescent bulbs, a halogen headlight works by heating a tungsten filament inside it, and the filament is a very delicate, thin wire capable of passing electricity.

Halogen bulbs get electricity from a source and pass it through the filament. It has a high melting point, so it heats up quickly and can thus produce light.

What Are Halogen Headlights

The difference between an incandescent bulb and a halogen bulb is that halogen bulbs use halogen gas to heat the filament. It shines brighter as more heat is given to the filament.

Do not touch halogen bulbs with bare hands as they produce a lot of heat and are hot to touch. The major drawback of halogen headlights is that they consume much electrical energy, but they have light in small amounts. In other words, its power consumption is very high, but output luminosity is very low.

What Are Led Headlights?

LED stands for “light-emitting diode” and is used widely in a variety of applications of outdoor lighting, including led lamps, led headlight bulbs, and more. LEDs consume less energy, less power, have a longer lifespan, and produce less heat than halogens, and LEDs also emit brighter light.

What Are Led Headlights

Compared to incandescent light bulbs, LEDs operate on diodes instead of filaments. The diode is a semiconductor device that allows electricity to pass through it, and that is where the LED gets its name from. The diode acts as a one-way switch, allowing the current to pass in one direction only. LED headlight bulbs emit heat, but it is far less than halogen headlight bulbs. Diodes also have fans and heat sinks to help keep them cool and increase their lifespan.

The LED bulb is more efficient and brighter than a halogen headlight. LED lights are in use instead of halogen lights in older vehicles since they increase the luminosity by forty to fifty percent as compared to halogen light bulbs.

Are LED Headlights Better?

LED vs. halogen headlights is a common topic of interest that often sparks a debate among car enthusiasts. Some argue that LED bulbs are better, while others prefer halogen bulbs.

The design of reflectors and headlight assembly play a vital role in the performance of the headlights, and it does not solely depend on the type of headlight bulbs used.

According to the Insurance Institute for Highway Safety, LEDs operate better than halogen bulbs, but some halogen bulbs outperformed LEDs. Generally, LED bulbs are preferable.

LED consumers and car manufacturers prefer bulbs since LEDs emit more light, utilize less power, and have a longer lifespan. They have brighter, whiter light than halogen lights which mostly give a yellowish light.

Halogen headlight bulbs were the gold standard for headlights in cars and most vehicles since they cost less. Now LEDs act as a halogen replacement for car headlights.

Difference Between Halogen Bulbs And Led Bulbs

Let’s take a look at the differences between halogen and LED headlights.

Halogen bulbs are incandescent and work using a tungsten filament. As current flows through it, heat is generated, and light is produced. Incandescent bulbs use argon gas, while halogen bulbs use halogen gas. Halogen headlight bulbs consume more energy and have a short lifespan, and they have more brightness than incandescent lights.

Difference Between Halogen Bulbs And Led Bulbs

An LED bulb uses a diode to pass an electric current that generates bright light while producing less heat. LEDs are 90% more efficient than incandescent bulbs due to lower energy consumption, so they last longer than other types of lights. LEDs do not burn out with time because they use diodes, which may dim over time.

LED bulbs are small and give the user the freedom to get creative with headlight assembly and reflectors. It is even used in LED lamps. The drawback of LED light bulbs is that they cost more than halogen bulbs and even high-intensity discharge headlights that use xenon bulbs.

Frequently Asked Questions (FAQ’s)

Let’s answer some questions involving LED vs. halogen headlights.

Are Led Headlights Brighter Than Halogens?

Yes, LED headlights are brighter than halogen headlight bulbs, and their luminous efficiency is 72 lumens/watt, while halogens have 25 lumens/watt. In simple words, LEDs have more brightness, with less energy used.

Does An Led Use Less Electrical Energy?

Yes, they use less energy. Additionally, LEDs come equipped with a heat sink and a fan that act as heat exchangers and save energy.

What Is The Advantage Of Using Led Headlights?

LEDs quickly light up when they receive current, compared to halogens that have an unavoidable delay. The compact size of LEDs allows users to get creative in the design of headlights, and they use lower energy but still give a bright white light compared to halogens.

What Are The Disadvantages Of Using Led Headlights

LED lights do not project light in every direction, so they should be placed appropriately so that you get proper illumination. When traveling in bad weather, LED lights often cast more glare. Even at every short-distances, you will experience more glare. Furthermore, LEDs cost more than halogens.

What Are Hid Lights?

Xenon high-intensity discharge (HID) lights are a recent invention. They use ionized xenon gas to send an electrical charge between electrodes. When we compare HID bulbs with LEDs, the former lasts for a shorter while. Although the intensity of their output light is excellent, they need some seconds to reach that full intensity. LEDs, on the other hand, light up instantly.

Can I Replace My Halogen Headlight With An Led Bulb?

Halogen light gets dim and dull over time, and owners use conversion kits to replace them with LED or HID lights. You can use an LED conversion kit for this purpose, but you need to check whether your vehicle is compatible with the conversion kit or not.


In conclusion, LED lights are brighter than halogens or incandescent bulbs. Even HID bulbs that use xenon gas require a few seconds to light up. LEDs give you quick results and light up in no time, which is especially useful. LEDs are more efficient in power, heat, and energy consumption.

Its small size makes it useful for use in various kinds of designs. So, to answer the big debate over LED vs. halogen headlights? The LED bulb is the superior choice over halogen bulbs and is a popular choice by car enthusiasts and car manufacturers.
