HID Conversion Kit Guide & FAQ

What to look for when buying or comparing HID Kit

Brightness: Brightness is measured in Lumen. The higher the number, the brighter the lights are. For Xenon HID, one bulb typically put out 3500 – 4000. Anything more than that is too much for the average Joes and Janes.

Compatibility: You have so many different sizes for bulbs;  H1, H3, H11, HB3, HB4, 9005, 9006, etc. Check the owner’s manual that comes with your car to see which size your car has. You also need to understand that not all halogen projectors are compatible with HID projectors. Double check with the seller if the kit will fit your car.

Ease of installation: Some kits are well-designed and made for plug-n-play. Others require a bit of elbow grease. Luckily, help is easy to find these days. Many Youtube videos can help you out with installation issues. Brand-specific installation guides are also easy to find.

Color: 8000K lights are great during clear weather but terrible in the rain. Your visibility will be very much compromised using them. Pick the color that suits your particular condition. For driving in the rain, for example, 4300 is the sweet spot.

Wiring and wiring harness. There are horror stories out there about wires and wiring harnesses burning out. Those kinds of stuff will happen when you choose a kit with low-quality wires and harnesses. HID bulbs drain high electrical current initially, up to 20 Amps. Skinny wires have high resistance, so when very high currents flow in them, they get too hot.

Customer Service. Sometimes, you just run into problems. When installation goes bad or parts break, you’d want a company that cares about their customer and doesn’t make you go through hoops and hurdles just to get a reply.

Projectors Are Kind Of Important

Scratch that. Projectors are vital for HID lights! A good projector cuts off the light to make sure you don’t blind oncoming drivers. High-quality projector is engineered to throw out light to the best of its abilities making the projected light clean and intense. A 35-Watt kit will beat a 55-Watt easily when you fit it with the right kind of projector.

While we’re talking about projectors, keep in mind that halogen projectors are not HID projectors. They are not the same beast. If you swap the halogen bulbs with HID kit while still using the halogen projectors, you will get glares. The light will bleed more past the cutoff line. If you insist on reusing the halogen projectors to save money, you will need to do slight mods. Replace the stock halogen lenses with clear lenses, for example. You also need to tinker with the shield on the interior to cover any spot that may produce glares.

Now, if your car headlights only have regular reflectors instead of projector lenses, you should never put your HID in them. You’ll be getting diffused light, blinding other people, and getting in trouble with the law for it.

By now, you should have understood that HID and projectors are inseparable. When you’re upgrading a pair of reflector headlamps, be sure to get good projectors with the HID. However, retrofitting projectors into headlamp housings can be labor intensive, and it’s something that should be done carefully by someone who knows exactly what he’s doing. 

Installing HID Conversion Kit

For a successful and trouble-free installation, you should start by selecting a plug-and-play kit. This means you won’t need to do any drilling, cutting, or any kind of customizing works. Now, the moment you receive the kit in hand, be sure to check content and see if it has everything you need like the bulbs, ballasts, wiring, harnesses, relays, mounting brackets/double sided tape/zip ties, and other mounting hardware. Don’t start anything unless all the necessary stuff is in hand. Double check the bulbs’ sizes to ensure they’re exactly as you ordered.

Next, is to read the installation instructions. Pay attention to the wiring diagrams to make sure you connect the wires correctly. Since we’re dealing with electrical here, be sure your hands are dry. You don’t want to get the shock

The next step is to remove the old bulbs from their housing and replace them with the new HID bulbs. Be careful when handling the new bulbs. Don’t let your hands touch them because the oil from your hands and fingers may cause the bulbs to break when you turn them on later.

Now, connect the wires to the ballasts and mount them following the instructions given. Different manufacturers have different ways to mount the ballast, but they have the same goal; to minimalize the vibrations that will compromise the ballasts’ performance.

Once the ballasts are secured, connect the wires from the ballasts to the bulbs and the wires from the ballasts to the power source from your car. When necessary, use electrical tape one the connections that may be exposed to the elements. This simple measure can help waterproof the connection, and also hold them in place tighter to ensure a long-lasting connection for years to come.

Okay, now that you know how to install HID kit, there is one more rule that you should be aware; don’t be afraid to ask for help.

If you’ve never done any upgrade to your car before or never done any electrical work on your car, it’s okay to feel a bit intimidated. For such a case, it will be best if you ask for help from a professional or a friend who knows the ins and outs of replacing standard car headlight with and HID one. There are many trivial issues that may seem huge by novices that actually have simple solutions.

One example of such issue is flickering. Flickering can be caused by improper grounding. The fastest solution is to use heavier gauge wire to improve the grounding contact and to choose a different location for grounding that you currently use. The electric current will flow more smoothly, and the flickering will be no more.

Difference Between AC and DC HID Conversion Kits

While you’re shopping around for conversion kits, you may see that there are AC and DC conversion kits. The AC types are the ones you will most likely get when you buy an HID conversion kit. Recently, however, some manufacturers also offer DC conversion kits.

The main difference of the two is the flow of electricity. AC HID lights use AC ballasts where electricity is alternating continuously to ensure equal distribution of ions. The direct result of this is that the lights produce stable output without any flickering. On DC ballasts the current flows in one direction only, and this makes DC HID lights prone to flickering.

In terms of durability, AC HID lights can last up to three times more than DC HID lights. The reason is that alternating current puts less stress on the components of the HID bulbs. If you’re aiming for long-term durability, AC is the one you want.


Picking the best HID kit can be quite a chore. However, the HID kit reviews above should cut some of the work off you. Any one of them is an excellent choice for your car. Be sure to contact the seller to check the kit’s compatibility with your car headlight. A simple call can ensure trouble-free installation. Don’t be shy to ask for help from a friend or professional if you don’t know what you’re doing or simply don’t want to risk it.
