7 Best Car HID Headlight Conversion Kits in 2023 – Reviews and Buying Guide

Most cars have halogen or LED headlights, which shine some light onto the road in front and use reflectors in the light bays. However, you may have seen more powerful headlights on the road, and want to upgrade your car’s headlights to these.

Car HID headlights (or high-intensity discharge headlights) are very strong and can be seen from the road. They emit blue light and are excellent for driving at night or in rainy conditions (and especially on rainy nights). HID lights are powered by electricity or gas, depending on the type.

LED and HID headlights are the premiere headlight exchanges. Most older cars are equipped with halogen lights, which use gasoline, aren’t as bright, and don’t last as long. However, HID and LED headlights are much brighter than halogen and last much longer.

LED lights last a little longer and are a little brighter, but can overheat if you’re not careful. HID doesn’t run the risk of overheating but doesn’t use electricity. There are pros and cons to each option, but both HID and LED are excellent choices for a headlight upgrade.

If you have an older car, you probably need to switch out the headlights for HID lights. Luckily, it’s a pretty easy job. All that’s needed is a lightbulb switch using a conversion kit.

When you’re looking for conversion kits, it can be easy to grab the cheapest kit and hope for the best. However, although it might be easy to install and save you money, some of the less expensive options can scatter the light from the headlights. This not only makes it more difficult for you but can blind oncoming drivers.

To truly make the best decision for your car and everyone’s safety, you need to buy the best HID headlight conversion kits available. Of course, this doesn’t mean you have to break the bank—there are plenty of budget-friendly options that are safe and high quality.

The Best HID Headlight Conversion Kits in 2023

We researched for you and found the best of the best, and here they are!

One of the biggest issues with finding good LED headlights is buying them for cars with unique headlight shapes. A Jeep is one of those cars—the factory headlights are never bright and they are round, which makes it extremely difficult to find headlights for anything less than a few hundred dollars. Once you install Cree Round ‎SL-0075A headlights and adjust the aim, you’ll be ready to hit the road.

Most of the time, you won’t even need the high beams with these lights. They are bright enough to get you through anything but the darkest country night or the thickest fog, so you don’t have to worry about high beams all that often!

Of course, these Round ‎SL-0075A headlights won’t be great if you don’t have a Jeep or other compatible car. However, for those who want the best for their vehicle with round headlights, you’ll be able to install them quickly and start seeing better results immediately.

Although Wisamic M020003 was made for the Harley Davidson Dyna Street Bob, this headlight is compatible with any motorcycle that uses a 5 ¾ inch headlight. This includes almost twenty different types of Harley Davidson motorcycles spanning the past thirty years or more.

Wisamic M020003 is incredibly easy to install, with a simple three-prong plug to attach to the bike’s wiring. After that, all you need to do is secure the headlight and you can ride away. The advertised 400% increase in light is no joke–these headlights illuminate the road for huge distances and are ideal for night or country riding.

With integrated high and low beams, you can switch back and forth without changing the area lit up by the lights. The LED is a softer light than many HID or LED lights, so it won’t blind oncoming traffic. Of course, the price is a selling point too, with these Wisamic M020003 headlights coming in at a fraction of the cost of similar products.

Even when you have HID bulbs, they don’t last forever. Dealerships and mechanics will ask for several hundred dollars apiece (plus labor) to install a new headlight bulb. It’s easier to buy your own and replace it after watching some online videos or instructional websites. That’s where these Philips 42302C1 bulbs come in.

The Philips 42302C1 bulbs work in any car that already has HID headlights. Unfortunately, you won’t be able to replace your halogen or LED lights with these bulbs without replacing the entire system.

Philips 42302C1 isn’t a conversion kit, but it is a replacement for an HID light. If you already have HID lights, these bulbs will pop in and out and are a cinch to replace.

When shopping online, make sure that the Philips 42302C1 comes with the proper coding technology: a QR code to take you to the Philips website.

Many companies try to make duplicates, but they will be a waste of time and money and not work well in your car. The QR code and certification are essential in any online purchase of HID bulbs.

The cons? Marsauto D3S are a little clunky and don’t fit in every headlight slot. The size of the bulb itself is the same, but the wiring for the Mars Auto bulbs is all in a box that fits behind the headlight. It can be harder to fit this box under the hood if your car has flatter or wider headlights.

However, one size fits most with the Mars Auto headlight bulbs, and there’s no question that Marsauto D3S are just as bright as the others. They work well as replacements for standard bulbs as well, although you’ll have to buy more accessories to switch HID bulbs for halogens.

Despite the clunkiness, Marsauto D3S’s relatively easy to install these headlights, with a simple plug opening in the bottom. If you get them in behind your headlight opening, they’re an excellent choice for the bluest light without breaking the bank.

You only need to take out your headlights, switch a few things around, and reinstall the lights. The HYBKLER CANBUS HID BALLAST will change the wiring from halogen lightbulb to HID, making it safe for you to install your brighter light bulbs without damaging the engine.

These HYBKLER CANBUS HID BALLAST are almost universally convertible, making them convenient for any car model. Of course, they aren’t necessary if you already have HID lights, but will come in handy for the big switch from halogen to HID. They come with a one-year warranty to ensure any damage or issues you have are resolved.

When you install these HYBKLER CANBUS HID ballasts in your car, you won’t need very many tools. Some cars have difficult headlights to take out, so that might make it more difficult, but the ballasts themselves attach directly to the wires leading to the headlights. With an HID lightbulb and a ballast, you can have HID bulbs in under an hour.

The most important thing to know about this Xentec 9006 (HB4) kit is that it isn’t compatible with every car model. To be sure that a kit is compatible with your car, you might need to buy separate ballasts and light bulbs. However, for the cars that do work with this model, you’ll be able to do the entire conversion with one kit.

Although the whole Xentec 9006 (HB4) kit is a little bulky, the company offers several different sizes (the link goes to the slim option). With these options, you should be able to fit both parts underneath your headlights with little to no problem. The entire Xentec 9006 (HB4) kit is budget-friendly, which can help if you’re redoing a whole car.

Although there is no guaranteed warranty on this set, the customer service department is excellent. If something breaks in shipping or goes wrong during installation, you will be able to return it and get a replacement or a full refund.

Make sure you’re following the instructions, however–it’s easier to get it right the first time.

The HID-Warehouse D2R / D2S lightbulbs are DOT approved, legal, and good for the roads, so they won’t blind other drivers or cause you to get pulled over. They also have both a high and a low beam, which is integrated depending on your headlight model. If you’re not pleased, you can return them under the two-year warranty!

The biggest con of these HID-Warehouse D2R / D2S bulbs is that they don’t last as long and they aren’t entirely compatible with every model. You’ll have to compare the existing models on your car to the type on the website to ensure they match. Ballast is also necessary–if your car didn’t come with HID lights, you’ll have to install one!

Like many HIG bulbs, these HID-Warehouse D2R / D2S bulbs have a quick plug-and-play installation and are easy to install or uninstall as needed. They come in multiple color options, from pure white to blue light. As long as your car is compatible with them, these headlights are an amazing budget-friendly solution for HID bulbs.

Before You Buy: Car HID Headlight Conversion Kits Buyer’s Guide

Now you have a list of excellent products to consider for your upcoming headlight conversion project. However, before you even start, you need to think about the various aspects of this job. When modifying your car, you are taking the responsibility of it into your own hands. Ensure that your conversion goes well with these tips.

Things to Look for in a Headlight Conversion Kit

If you’re wondering how to choose the best headlight conversion kit, you need to assess what your personal needs are.

There’s no one universally accepted “best,” because there are several types of cars, headlights, and budgets to take into account.

Here are some factors to look at when you’re thinking about switching headlights.

Compatibility

This post gives suggestions for headlights, ballasts, and bulbs, but it’s up to you to make sure they will be compatible with your car. A quick Google search should work, especially if you have the make and model handy.

DOT Approved

When you buy any kind of car modification, it’s essential to know the legality of the change you’re making. Headlights are regulated, and there are plenty of illegal HID and LED headlights on the roads.

If you don’t want to get a ticket while driving with your headlights on, make sure your lights are DOT approved and road legal. This should be obvious by a DOT engraving on the front of the headlight or the side of the bulb. It will also be advertised as part of the bulb or light.

Price

Of course, the price is a huge component. If money was no object, you could just bring your car to a mechanic and pay hundreds to a thousand dollars for a headlight switch. However, you want to save some money and do it yourself. So make sure you’re remaining within your budget.

Quality

Even if you’re trying to save money, you don’t want to buy the cheapest kit on the market, only to realize that it doesn’t work and your headlights aren’t street legal. Instead, do your research (well, we’ve already done it for you) and make sure you’re getting high-quality parts so they’ll last forever.

Components

When you buy a kit, you will either have to buy the ballast and bulbs separately or buy them together. Whatever you do, make sure that you have both components. Budget for this as well–if you only buy bulbs, they won’t work without a ballast and vice versa.

HID Vs. LED: Which Is Better?

One of the biggest arguments in the high-power headlights world is whether HID or LED is better. Although we focused more on HID headlights in this post, there are some points to be made for LED lights as well.

Here’s the breakdown:

• HID lights tend to have more power, but don’t last quite as long
• HID lights are powered by gasoline and heat, while LED lights are powered by electricity
• HID lights don’t run the risk of overheating (LED lights need an extra component for safety)
• Both are blue or white lights
• Both are equally easy to install and replace
• Both last much, much longer than halogen lights (and are up to 400% brighter)

With these facts, the decision to make for your car is really up to you. It’s usually easier to find HID bulbs and ballasts, while LED lights are premade and put into headlights. If you have a specialty car, you might have to work a little hard to find an HID light bulb that works for your vehicle.

HID bulbs are usually accepted as superior lights for strength and color. LED lights, on the other hand, work the best for longevity. The experts are pretty divided on this issue, so it depends on where you stand and your car’s make.

However, both of these lights are vast improvements over halogen lights, both in longevity and strength. Whichever one you end up choosing, you’ll be making a good decision for your headlights, safety, and the car itself.

Things to Know Before Hitting the Road With Your New Headlights

Now that you’ve made your decision, bought your kit, and finished the conversion, you might be ready to get on the road. However, there are a few things to keep in mind before you show off your new, high-power headlights to the world.

Aim Your Headlights

If you are replacing the entire headlight (in a Jeep or another custom-shaped headlight), you will need to aim your lights. Factory-installed headlights are aimed to be at a specific height so that other drivers aren’t bothered by the brights or standard lights. It’s especially crucial to adjust this height when you add the brightness of HID or LED lights.

To aim your headlights, play around with their tilt and height until they’re pointed downward and forward. You want to see the road ahead of you, but not blind other drivers and get flashed for having your “brights” on when they’re not. You can also adjust your headlights in a regular car.

Check the Hi-Beams Settings

Some HID and LED headlights automatically turn to high beams. This is problematic if you don’t want to blind other drivers (and we assume that you don’t). It also doesn’t work well if you live in an area that requires headlights during the day.

Check the settings and test out your new headlights before hitting the road with them. You will be able to tell the difference–just know which set belongs to the high beams and which one is regular strength.

Are HID Lights Legal on the Roads?

One of the most common questions we get about HID headlights is: are they legal in the United States? Well, that’s somewhat of a complicated question. First of all, any factory-installed HID headlights are legal without question. If your car came with HID headlights, you are driving legally.

Otherwise, it can become difficult, because of the legality of post-purchase modifications. However, as long as you buy headlights with the DOT insignia etched on them and make sure that you’re aiming them, you should be fine. The legality becomes an issue if the headlights are affecting other drivers.

Wrapping Up…

Now you have available to you a list of the best car HID headlight conversion kits. You also know what to consider when choosing one.

Be sure whatever kit you get has the DOT insignia to ensure you won’t get in trouble on the road. When you’re installing your HID lights, aim them down, the way your original headlights were installed, to prevent blinding other drivers

Most important of all, make sure whatever you buy is compatible with your particular vehicle. There’s nothing worse than getting excited about your new conversion kit only to not be able to use it!

HID headlights can absolutely enhance your driving experience, especially for long night drives.

What you need to do next is just click on the link of the one you prefer, and you’ll finally have the headlights you’ve been wanting.
