Seeing clearly when driving, especially at night, is arguably one of the most important factors for driving safely.
Although some newer luxury vehicles are now starting to come with LEDs or HIDs by default, over 95% of cars on the road, old and new, are still equipped with halogen bulb technology.
Many drivers are tired and frustrated with the dull, yellowish light output from halogen headlight bulbs and as a result, we frequently get asked: “Can I put LED or HID bulbs in my stock halogen headlight?”. The good news is that, yes, you can.
In this article, we’ll dive into this question in greater detail, how halogen headlight conversion kits work and other alternatives available to you.
Now that you know that you can replace halogen bulbs with either LED or HID bulb conversion kits, you are probably wondering how they work.
Both LED and Xenon HID conversion kits are essentially composed of headlight bulbs that are perfectly compatible with stock halogen headlights. The main difference between the two, aside from the different technology, is the accessories that come in each kit.
LED headlight conversion kits include a set of bulbs and LED drivers. The bulbs produce the light and the drivers regulate the flow of current from your vehicle to the LED bulbs, essentially making the LED bulbs compatible with your vehicle.
The LED bulbs will have an identical design to your halogen bulbs in terms of both the locking tabs and plugs. So the bulbs will lock in perfectly to your housing and connect right to your car or truck’s power harness.

HID headlight conversion kits are very similar. HID kits include a set of bulbs, ballasts, and ignitors. The bulbs produce the light while the ballasts and ignitors regulate the flow of currently from your vehicle to the HID bulbs, essentially making the HID bulbs compatible with your vehicle.
Like LEDs, HID bulbs have an identical design to your stock bulbs with respect to both locking tabs and plugs. The HID bulbs will lock in tightly to your housing and connect perfectly to your vehicle’s power harness.

So now you know that you can put LED and HID bulbs in your stock halogen headlights and understand how it works on a high level, you are likely wondering how much these kits cost.
As a general rule of thumb, HID kits are about 30% to 50% cheaper than LED kits and for either technology, pricing varies with quality.
In fact, installing LED headlight or fog light bulbs is identical to installing halogens, which should take, on average, no more than 10-15 minutes per headlight, assuming a typical Plug & Play kits.
LED headlight bulbs can be found for as little as $60 per set and can go up to the $200-$300 price range, however, you can find high-quality, reliable and durable kits for around $120.
Cheap kits, typically under $100, are not recommended at all. They often operate on very high wattage which can damage your headlight and vehicle’s power supply, the light quality and distance are poor, they will burn out after a few months and come with little to no warranty.
High-quality bulbs, on the other hand, will operate at the same wattage or lower than your stock bulbs, they will produce an incredible and far-reaching beam, they will last very long and come with impressive warranties. Learn more about Finding the Best LED Headlights.

When it comes to improving your car or truck’s light output by switching to LED or HIDs, there is another alternative, retrofitting your entire headlight assemblies.
Retrofitting means completely replacing your headlight assemblies with new ones that carry HID or LED bulbs by default. Depending on the quality of the product, the design of the headlight, and other key factors, retrofitting can cost anywhere from $400 to over $2000 (excluding labor costs).
Although more expensive and will likely require the expertise of a mechanic or performance shop, retrofitting your headlight assemblies is definitely a great option. Some assemblies even have neat, modern-looking halo designs.
One caveat of retrofitting is that changing the bulbs when they burn out is tricky, not in terms of changing the bulbs but actually finding the bulb. It won’t be required very often so it’s not a big concern but helpful to know.
