HID Conversion Kit Buying Guide

HID conversion kits allow you to convert your traditional headlights to bright xenon bulbs. You can have the best headlight bulbs in the world but halogen will never be as bright as the HID alternative. These are some of the brightest bulbs on the market and will give you the brightest possible light from your headlights.

To help you make an informed buying decision, we have produced the below guide regarding aftermarket HID conversion kits.


One of the best benefits to installing HID xenon bulbs is that they come in a variety of different colors. The choice varies from yellow, white, green and much more but you will want to check that they are street legal within your state beforehand.

Many enthusiasts will customize the colors and use different colors for each type of lighting. For example, you may use a bright yellow color output for the fog lights and then the desirable white light for the main headlights.

Different Color HID


Something that’s very important to look at when shopping for HID conversion kits is the wattage. Ideally, you’ll want a kit that comes with 55 watt bulbs, which are the brightest. These bulbs put out up to 5,000 Lumens and provide additional brightness. However, some kits are only wired with a 55 watt ballast and a 35 watt bulb..

The 55 watt ballast helps create very bright beams without the actual bulb, but it’s still not quite as bright as if the bulb had this wattage itself. If you do get a 55 watt bulb, just keep in mind that you may need to do some extra wiring to install the headlights.

Ballast Type

HID conversion kits come in two different ballast types, which includes an AC or DC. The AC ballasts often cost more but they are better at regulating the heat and voltage running to the headlight. This has the result of extending the lifespan of the HID bulbs.

Ease of Installation

Many manufacturers state that their HID kit is “plug and play”, which means they are simple to install. However, before you even get to the installation, you will want to ensure that the bulb you choose is the correct size for the bulb housing of your car.

We highly advise that you check the contents of the kit and ensure that it includes the bulbs, ballasts and mounting hardware. Many cheap options forget to include additional accessories, which can make installation far more complex than it needs to be.

Beam Configurations

A unique feature that some HID kits offer is the ability to configure the beams into different shapes and patterns. You can specify the exact beam that you require to best suit your light requirements. These include anything from a narrow to round beams.

Depending upon whether you are using the HID conversion as off road lights or simply on the road, the beam can make all the difference.

Car HIDs


Durability is another important factor to consider when searching for an HID conversion kit. Most manufacturers will state a lifespan of the bulbs, which can be anywhere from 10,000 to 50,000 hours of service life.

As mentioned above, many people may use HID lights for off road use, which means they need to be durable. For this reason, many brands will use high grade silicone and a shockproof design to make their kits more desirable.


A premium aftermarket HID kit can completely transform the vision you have of the road during the night or in bad weather conditions such as fog. Most kits come with everything you require for a simple plug and play installation, which can take as little as 20 minutes.

All of our recommendations cover HID kits suitable for all budgets and AC or DC ballasts. We advise that you check for a warranty and ensure that the kit comes with all the mounting hardware to make the installation simple as possible.
