In a similar fashion to LEDs, HID headlights offer brighter light than halogens at a higher level of efficiency. This is a factor that is very important for locations where constant high-power lighting is required. They provide a whiter light and are twice as efficient as halogen lights. We most often see HID lamps used in the lighting of large areas, such as street lamps and flood lamps in stadiums. It differs from both halogen and LEDs in that the source of its light is an electric arc that takes place between two tungsten electrodes. It is often referred to as a xenon light, referencing the gas that the bulb contains. Most manufacturers promise that, with proper care, their LEDs will survive the lifetime of the vehicle they’re fitted to. The cooler the operating temperature, the longer it will continue to function. The lifetime of an LED light is most closely linked to its operating temperature. This is a potential cause of fitment issues and something one should check before purchasing a kit. Heatsinks are usually located at the back of the bulbs and can extend up to an inch.

In some instances, this can be a simple heatsink, but more often, a fan is also included to ensure the flow of cool air over the heatsink. As a result, high-power LEDs require cooling mechanisms to ensure they don’t overheat. Less than a halogen, but because LEDs are so small, this heat is concentrated in one spot.

This can confuse the computer systems within cars, so the extra electronics are used to increase the voltage drop and avoid errors.Ĭontrary to popular opinion, LEDs do generate heat. The main reason for this is that LEDs operate at a lower voltage than the conventional 12V that a car provides. Both options require additional electronics between the car and the light. It also requires the least modifications to your car. This is significantly more expensive, and the LED kit option is thus much more popular. The alternative is purchasing an entirely new headlight fixture. This comprises LED bulbs that are shaped to be drop-in replacements for conventional halogen bulbs. The biggest is the replacement LED kit option. The aftermarket LED scene has two sections at the moment. This results in an overall safer environment for night driving for all road users. What this entails is that the road directly in front of the car can remain brightly lit, whereas areas occupied by oncoming traffic have only a dim light shining at them. This system allowed them to dim certain sections of the light while allowing the rest to remain bright. Audi, for instance, had a headlight on the 2013 A8 that had 25 individual LEDs per headlight. In 2007 Audi revealed full-LED headlights in the V10 model of their R8 sports car.īecause LEDs can be manufactured in various sizes, several nifty applications have been developed with them. Lexus was the first manufacturer to include LEDs in their headlights in 2006, but it wasn’t a complete implementation. Additionally, in low current applications, they also generate minimal heat. Their small nature and low power consumption make them perfect for such applications. You’ll see them on your cellphone and laptop, even ones that are 20 years old. One advantage of this form of light generation is that by adjusting the material properties of the semi-conductor, one can adjust the frequency of the emitted light, thus changing its color. If you really want to get into the details of this, check out How Stuff Works article on the topic.

This movement of electrons generates light. Instead, an LED transfers current through a semi-conductor. Unlike halogen bulbs, LEDs don’t have a filament that current is passed through.

Light Output: LED and HID headlights both have excellent light output, but LEDs illuminate instantly, while HIDs take a few seconds to achieve full brightness and proper color.

Longevity: LED headlights have unmatched longevity compared with HID and especially halogen headlights.

LED headlights win the comparison against HIDs narrowly for a few reasons: The sun’s color temperature at noon is 5500K – 6000K. Headlights whose light output most closely matches the sun’s color temperature tend to be the most effective for the human eye. The Light intensity is quite weak for the halogen and HID, while the LED bulbs have a very tightly concentrated, focused beam right near the center, with a strongly curved beam emanating from the center.Īlso, the color is higher on the Kelvin scale, coming in the right around a 6000K color, while the HIDs are closer to 5000K, and the Halogens at a 3500K or so. In this case, I’ve swapped one of the halogen bulbs for a LED bulb. From the factory, it’s equipped with HID low beams and halogen high beams. This example uses the headlights of an Infiniti G35. The image above demonstrates a clear advantage of LED headlight bulbs.
