Converting Halogen to LED Headlights

Updated: Apr 6, 2023



The Benefits and Drawbacks of Switching From Halogen to LED Headlights


The four primary types of bulbs available for use in vehicles are halogen, xenon, laser, and LED lighting systems. While halogen lights have been the norm for automobiles in the United States since the 1970s, a few automakers are transitioning to LED headlights for their models. LED lighting provides manufacturers with greater lighting design freedom and dependability in electric or hybrid vehicles.


Some automobile owners replace their halogen bulbs with aftermarket LED lights. Each type of headlight bulb has advantages and disadvantages. If you intend to replace your halogen lights with LED bulbs, be aware of the benefits and drawbacks. Here's everything you need to know.


The Benefits of LED Headlights


LED headlights are becoming increasingly popular and for good cause. They provide various advantages, which are detailed below.


LED Headlamps Consume Less Energy


The minimal power consumption required to run LED lights is one of the primary reasons for the move from halogen to LED lighting. LED headlights consume a fraction of the energy required to power traditional halogen headlights. With reduced power pressure on your system, your battery and alternator will last longer. If you keep the headlights on while the car is not running, your LED headlights may not draw enough power to destroy the battery. If your halogen lights are mistakenly left on for too long, they will leave your battery inoperable without a jump-start.


LED headlights have a longer lifespan.


Halogen headlights are significantly less expensive than LED lights, but their lifespan is limited to 1,000 to 6,000 hours. LED lights can provide 25,000 to 30,000 hours of continuous vehicle lighting. The LED bulb's extended life is a significant benefit for persons who:

  • own a variety of cars

  • regularly travel large distances

  • inability to maintain their own vehicles

  • live far away from the nearest auto parts shop

In certain vehicles, changing headlight bulbs is a difficult task. Experts advise not touching the glass shell of a halogen bulb when replacing it. Grease and other particles on your hands might contaminate the bulb glass. When that greasy or oily covering warms up, it can harm and shorten the life of the halogen bulb. LED lights are less susceptible to grime on your hands. When changing LED headlight bulbs, you don't have to be gentle. This element greatly simplifies the laborious job of swapping out lights.


The Drawbacks of LED Headlamps


Despite their benefits, LED headlights are not without flaws. Here are a few drawbacks to consider.


Lighting From LEDs Is Not Omnidirectional


Halogen lamps shine in all directions. This means they emit light from the bulb's front and sides. They give ample illumination of the road ahead as well as the road edges.


Each diode in an LED light emits light in a straight line. The light generated by an LED array is significantly more bright than that produced by a typical halogen lamp, yet this does not always convert into superior driving illumination. Unless the LED bulbs are correctly aimed, you will have headlights that do not illuminate as much of the road.


If you raise your car with larger tires or a new suspension, you must reposition the bulbs. Otherwise, the lights will be aimed too high or too low for your and other drivers' safety. LED lights pointed too high can cause other drivers to go blind, while LED headlights set too low do not illuminate enough of the road ahead.


Not Enough Heat Is Produced by LED Lights


Halogen headlight bulbs reach temperatures of about 4,500 degrees Fahrenheit. The heat they produce is great in melting snow, ice, and freezing rain from your headlight lenses. LED headlights produce heat at the rear of their lamps. To disperse heat, some versions use fans or braided heat sinks. When the lights are turned on, they produce relatively little heat. They aren't intended to melt snow off your car's headlight lenses.


When you travel in snowy or icy circumstances on a frequent basis, your headlight lenses become frosted up, even if you have LED lights installed. Several designs have been developed by automakers to remedy this issue, but in many cases, the modifications are insufficient. Experts recommend that if you travel in cold, rainy weather with LED headlights, you keep all of your car's running lights on while driving. Stop often to inspect your lenses for ice and snow accumulation. To avoid having snow slip over your hood and onto your headlights, clean all snow from your automobile as soon as possible.


If you're having difficulties seeing the road, have your body shop mechanic reset all of your headlights. Some LED headlights require replacement lenses or specialized housing to effectively reflect light on the road. Your mechanic can install these components without jeopardizing the headlamp assembly's water tightness. You should also be aware that in some regions, LED headlights are not authorized. Your local auto shop can inform you if LED lights are allowed on the road in your area.
