LEDs and HIDs require less power as a bulb to run, although the amounts are minimal. LEDs have a much longer lifespan than HIDs and halogen bulbs – easily long enough for the entire life that you’ll own and use the car, even if you spend a lot of time driving at night. Otherwise, LEDs and HIDs could easily blind oncoming drivers. With brightness and effective distance being so much better, it also means that the proper directing of light is vital. Effective distanceĪgain, LEDs and HID massively outperformed old halogen bulbs on effective distance, trebling what halogens were capable of. LEDs are slightly brighter, but the impact on your ability to see between LED and HID is minimal – both do a great job. Criteriaīoth LEDs and HID headlights are much brighter bulbs than old halogens. I’ve included halogen too, because it’s interesting to see how much better the modern headlights are compared to older bulbs. HID vs LED Comparison Tableįor the sake of comparing, let’s look at a number of criteria. They each have pros and cons, so let’s put them side-by-side so you can see which is the better choice. Two very different technologies, and yet both are popular in modern headlights. The bulb contains an inert gas (usually xenon) and two separate conductors.Ī current is passed between the conductors, arcing through the gas, which causes a reaction that then generates light. HID stands for High-Intensity Discharge, and they work very differently.

Light is generated when a current is passed through a semiconductor in the diode. LED stands for Light Emitting Diode, and they are entirely electronic light. Key Differences Between LED And HID Headlightsīefore getting into the performance comparisons, it’s good to understand the different technologies and how they work.Īs this will give you important context for why the bulbs perform differently. Whether they’re compatible with halogen housing.The key differences between LED and HID headlights.That only scratches the surface, though – there’s a lot to compare between the two different bulb types, so let’s take a look at: Both work well in projector housings, but LEDs are better in reflector housings, provided you get a matching bulb for your car or replace the bowl.

LED headlights are longer-lasting and brighter than HID headlights but HID are cheaper. What’s the difference between them, and which is better? The days of halogen bulbs being the go-to choice for car headlights are being left behind in the dust – now it is very much about the newer LED and HID options.īoth of these technologies have existed for a while, but it’s only in the last few years that they’re becoming prominent in car headlight manufacturing.
