Best HID Kit 2017 – Reviews & Buying Guide

High intensity discharge lights, or HIDs for short, replace the normal filament found in a halogen light bulb with a capsule of gas. The light produced by this gas is two to three times stronger than that radiating from a halogen light, which is why HIDs make one of the best upgrades you can make to your car. But you already knew that, it’s why you’re here in the first place. To help you choose the best HID kit for your car we’ve reviewed five of the best HID kits. Before we get into the details of the kits however, there are three things you have to know in order to make the right purchase.

HID Kit Bulb Type

The conversion kit has to match your already existing halogen headlight housing. Basically, there are over a dozen type of halogen bulbs in existence (9003, 9006, H1, H4, H7, H11, and so on). When purchasing a HID kit you want to make sure that the bulb matches or otherwise it won’t fit in the existing socket for it in your headlight housing. Your car’s manual should list the type used but if it doesn’t, check online. Most newer cars use H4 and H7, but 9006 is still common on a lot of pickups. If you are still unsure, Amazon got a great tool for checking the compatibility of HID kits with your car.

HID Kit Bulb Color

The color a light bulb emits is measured in Kelvin (Color Temperature). Your normal halogen bulb emits a color temperature of 3200K. That’s that slightly yellowish color most cars with halogen lights produce. Factory HID setups emit a color with 4300K, which is almost purely white with some yellow in it. Above that, you have 5000K and 6000K, the latter of which emits the slightly blue tint most premium cars have. Anything beyond that isn’t white at all. For instance, 10,000K is strong blue while 12,000 turns almost purple.

HID Kit Wattage and ballast

It’s the ballast’s job to provide the necessary voltage and current to the light bulb for it to work properly. Usually they come in 35W or 55W variants, but it’s not uncommon to find 75W ballasts as well. The stronger the ballast the more power the bulb will emit but the faster it will wear out. The difference from 35W to 55W, although not negligible, is small. If you want the most light output go for more Wattage, but if you want the maximum lifespan possible, the best hid kit for you is one with 35W.

XtremeVision 35W HID Kit Review

Best HID Kit - XtremeVision 35W HID KitXtremeVision is a well-known HID manufacturer with great plug and play kits. This particular kit comes with two premium slim ballasts for easy installation and a clutter-free engine bay, along with a massive choice of bulb types. They offer almost every bulb type ever created, from H1 and H3 to 9007 and 9012. You can choose from 9 different colors. The kit overall is very durable and reliable. The only reported issue as far as reliability is concerned falls down to the ballasts, which can suddenly die for no apparent reason, but as that happens after thousands and thousands of miles it isn’t a big issue. The bulbs themselves last 5 times longer than normal halogen bulbs though.

It’s a very solid HID kit overall. We’d recommend you avoid any color higher than 6000K, as the actual light output starts decreasing beyond that and you don’t see as much since it isn’t white light. The XtremeVision HID kit even comes with a 2 year warranty for peace of mind. You’re unlikely to ever need it thought, because especially at 35W this HID kit will last a long time.

Innovited AC 55W HID Kit Review

Best HID Kit - Innovited AC 55W HID KitInnovited as a brand isn’t as recognizable as XtremeVision, but their kit is just as good. The Innovited too comes with slim ballasts saving space in the engine bay and making installation super easy. The color range is the same as the XtremeVision but depending on your bulb type the Innovited kit comes with either a bi-xenon setup or a low beam xenon/high beam halogen one. Essentially bi-xenon setups just mean that a single bulb is in charge of operating both the low and the high beam, switching between different modes depending on what you want. The other one is self explanatory. Low beam is xenon and high is halogen with a different bulb.

So far the good sides. As for known issues, an occasional ballast issue may occur in the form of flickering or not powering up at all. Turning the car off and on will usually solve the problem unless the ballast died. Plus it’s a 55W kit. If you want the extra light, prioritize Innovited over XtremeVision.

XENTEC H4 6000K HID Conversion Kit Review

Best HID Kit -XENTEC H4 6000K HID Conversion KitXENTEC is a relatively well-known manufacturer of HID kits, with good quality products on offer. This particular 35W kit is no exception. It comes with two standard ballasts which are slightly larger than slim ones, but it does offer anti-flickering technology to reduce the amount of flickering the bulb can exhibit. Once again you can order it in a variety of sizes and colors but insufficient power to the ballasts may result in poor functioning of the bulb. A simple relay harness will solve the issue by redirecting electricity to the ballasts straight from the battery.

The kit is one of the simplest to install and also of high quality, giving you the feeling that it will last for a long time. That said however, the only real downside is the fact that the bulbs can occasionally differ in color slightly even if they’re the same actual color temperature. Nothing too major or noticeable but it’s definitely there in some kits.

SDX HID Headlights Xenon HID Kit Review

Best HID Kit -SDX HID Headlights Xenon HID KitSDX’s HID kit blends ease of installation in a powerful and compact package. The two slim ballasts are exactly that, slim, and can fit into just about any space in the engine bay. It’s available in all the different colors most kits come with, ranging from pink through white and baby blue, to completely purple. Amongst the 4 different kits we reviewed so far, the SDX HID kit has the most positive reviews on various forums. It’s not difficult to see why. The SDX HID Kit is both the most compact HID kit and the most reliable HID kit. A straight plug and play kit that really lives up to its name.

Contrary to the other kits on this list, the SDX doesn’t suffer from ballast issues as much. One of the bulbs can be slightly off-color compared to the other one but it isn’t that noticeable. Take care when installing the bulbs and wear gloves, since the body oils from human skin can contaminate the bulb itself and significantly decrease its lifespan.

Kensun HID Xenon Conversion Kit Review

Best HID Kit - Kensun HID Xenon Conversion KitThis isn’t just an HID kit, but it is the definitive HID kit. It’s the most popular option and as it turns out the most reliable one too. First off you have the extremely nice suitcase packaging it comes in which prevents any sort of transportation damage. The contents inside are arranged nicely with no chance of breaking. That’s already a major plus it has over most other HID kits.

Then we get to the actual kit itself and things start looking even more up. You can order it in all sizes and colors, but perhaps the most important thing is that it comes with 2 years warranty. It is by no means the most compact kit on the market, especially since it boasts premium ballasts, but it is the best performer. It’s a plug and play kit with no hassle.

Conclusion

Five different HID kits for five slightly different markets. Each is the best HID Kit for their own niche. The XtremeVision is a great 35W kit for almost any application, but you want the Innovited 55W HID kit if you’re after more lighting power. XENTEC offers excellent reliability if you don’t mind the small nuisances it can bring, and the SDX is one of the best all-rounders on this list. That said, none can top the Kensun. Its amazing packaging, stellar ballast and reliable bulbs make it our top choice.
