When it comes to the car headlight technology, halogen bulbs have been the standard for many years. However, many drivers are tired and frustrated with dim, yellowish light output of halogen bulbs and wondering is it worth to switch their OEM halogen headlight bulbs for LEDs?
The answer is YES. Many LED headlights have the same light-emitting position as halogen bulbs, which ensures the safety of the light pattern. The easy installation of LED bulbs allows car users to upgrade their halogen bulbs themselves.
If you plan to convert your halogen to LED headlight bulbs, this blog will provide you a complete guide.
A halogen bulb is a type of incandescent bulb that contains a tungsten filament enclosed in a small quartz capsule filled with halogen gas, such as iodine or bromine. When an electric current is applied to the filament, it heats up and emits light.
When the driver turns on the headlights, electricity flows from the car’s battery to the headlight bulb. The electricity heats up the tungsten filament inside the bulb, causing it to emit light. The halogen gas inside the bulb helps to improve the bulb’s efficiency by recycling evaporated tungsten back onto the filament, reducing the rate at which the filament burns out.
What is LED Headlight Bulb?
LED bulbs in a car work by converting electrical energy into light. LED stands for “Light Emitting Diode,” which is a semiconductor device that emits light when an electric current flows through it.
When you turn on your car’s headlights, an electrical current flows through a circuit that powers the LED bulbs. The current flows through a small chip inside the LED bulb called a diode. As the current flows through the diode, it excites electrons in the material, causing them to release energy in the form of photons, which are packets of light.
Is It Worth Converting Halogen With LED Bulb in Car Headlight?
Generally, converting your vehicle’s OEM halogen headlight bulbs to LEDs is possible and worth it.
However, you should also know the pros and cons after changing your halogen bulb to LED headlights.
Pros of LED Headlight Bulb Conversion

Can Halogen Bulb Replaced By LED In Car Headlight?
When replacing halogen with LED bulb in you car, you may be confused about several problems. Can halogen bulb directly replaced by LED bulb in car headlights? Do I need to make any modifications to my car to install LED bulbs? Will LED bulbs produce blinding light? Now we will explain from the following three aspects:
1.Optical
Replacing halogen with LED bulbs in your car means you will install LED car light bulbs in either projector or reflector headlight assembly.
To enhance illumination, a projector headlamp employs a lens in front of the light source to concentrate the light and produce a more precise and focused beam. Additionally, their convex lens protrudes, making them visually appealing even when they are not turned on during the day.
A reflector headlight is a type of headlight that uses a curved reflector to reflect the light emitted by the bulb. The reflector is designed to focus the light in a specific direction, creating a beam pattern that illuminates the road ahead.
The halogen bulbs will deliver a safe light beam pattern no matter in projector or reflector headlight assembly. The light source won’t blind pedestrians and oncoming traffic.
That’s to say, if the LED headlight bulbs you choose have the same lighting position as halogen filament, then the better light beam pattern as halogen bulbs.
2. Structure
When switching from halogen to LED bulbs in a headlamp, it is important to make sure the LED car bulbs can be fix to stock halogen housing easily. Whether automotive LED headlight bulbs can be installed on the original halogen headlight assembly is dependent on their structure to some extent.
- Size And Shape:
Halogen bulbs usually have a standard size and shape that fits snugly into most headlight housings. However, there is no official standard size and shape for LED car headlight bulbs on the market. As a result, LED headlight bulbs on the market come in a variety of shapes, and some are designed to be too large or too long to fit in the assembly.
- Heat Dissipation:
High-power LED car bulbs generate lots of heat to some extent, so they require different cooling mechanisms. This can lead to larger or more complex bulb designs that may not fit easily into the housing.
- Wiring And Holder:
This will decide if the LED headlight bulbs can be locked firmly into your OEM headlight housing and connect to the power plug of your car.
However, with the latest LED headlight bulb technology, most LED car light bulbs on the market are designed to fit within the space of a halogen bulb, allowing for easy installation without any modification.
3. Compatibility
Converting your halogen headlight bulbs to LED maybe will encounter compatibility issue such as the lamp not lighting up, the lamp flickering, or the dashboard displaying a warning.
- Voltage
Another reason why installing an LED bulb into a halogen housing can be difficult is due to compatibility issues between the two types of lights. Halogens operate at 12V and with a power of 55W, when the vehicle is in operation, the power supply is typically between 13-13.5V. According to the regulations, the automotive LED bulbs must be able to operate normally between 9-16 Volts.
Nowadays, many LED headlights in the market work with a voltage of 9-16V, and some can even adapt to a voltage of 24V. This allows LED lights to work normally in halogen lamp assemblies.
- Canbus Errors
If your vehicle’s lighting is not meeting the expected wattage, the Canbus system will detect it and flag it as a fault, leading to an error message being triggered. This fault is referred to as a Canbus error because it is caused by the car’s Controller Area Network (CAN) system detecting a problem with the bulbs. The CAN system is designed to detect any changes in the electrical load of the vehicle and adjust accordingly.
The good news is most aftermarket LED headlight bulbs carry with intelligent Canbus driver, which means that it can smooth out the power demands of your new LED bulbs and helps system adjust to the aftermarket product.
The Best LED Headlight Bulb For Halogen Upgrade
NAOEVO NR Rocket Design LED Headlight Bulb
If you are looking for quality LED headlight bulb that is close to halogen standard, but much brighter than halogen, we will highly recommend NAOEVO’s NR series LED headlight bulbs. With unique rocket design, these brand new NAOEVO NR LED headlight bulbs are designed to produce standard light beam as halogen while also enhancing brightness.
1:1 Design As Halogen
As we mentioned above, LED headlight bulb that has the same lighting position as halogen will ensure that the light beam pattern remains consistent with the original design of the vehicle. The the lamp bead is too front or too back, it can cause issues such as poor visibility, glare, and blinding other drivers on the road.
In this case, the NR LED headlight bulbs are designed as small as possible so that they can remain a mini size as halogen and the same lighting points of halogen bulbs. Thanks to 1.5 mm ultra-slim copper substrate inside the bulb, there is a narrow space between two lamp beads, which can greatly simulate the thin tungsten insides halogen lamp.
