Guide to HID Conversion

HID conversion is suitable for most vehicles fitted with halogen headlights from the factory. The conversion is fully reversible so long as you keep your halogen bulbs.


First you need to visit the Sylvania Website and enter your vehicle information, which will give you your bulb type. Below are two examples for possible results:

EXAMPLE 1: 2009 Honda Civic - this example below shows two separate bulbs for the high and low beam. This vehicle would require two single beam HID conversion kits if the owner wanted to upgrade both the high and low beams to HID. Alternatively, just the low beam could be upgraded.

EXAMPLE 2: 2009 Ford F150 - this example shows a dual beam headlight bulb which means both the high and low beams are built into a single bulb. The owner of this vehicle would need to purchase a dual beam HID conversion kit which would upgrade both the high and low beams to HID using just the one kit.

If for some reason you can’t find your vehicle bulb information listed on the Sylvania site you could try these other methods:

  • Check your vehicle manual
  • Contact the vehicle manufacturer via your local dealer
  • Remove a headlight bulb and read the bulb information
  • Email MotorFiend to ask us to check it for you


HID lights are color rated by a system know as Kelvin (K). The number describes the color, not the brightness of the bulb. The full range of HID products are the same brightness, which means no matter which HID kit you choose you will be upgrading to super bright headlights.

The color temperatures range from yellow toned 3,000K which is most suited to fog light applications to 12,000K which is a purple toned HID. If you are simply looking for better night time visibility for safer driving we suggest the 4,300K pure white HID kit.


MotorFiend's ballasts are available in regular, slim or CANBUS. All are digital ballasts, AC and have a 35 watt output. The slim ballasts are significantly smaller, therefore easier to fit into small spaces. CANBUS ballasts are recommended for all modern vehicles with daytime running lights or electronic headlight systems such as light sensors or auto shut off.

You’ve probably seen other cars on the road with these super bright colored headlights and thought to yourself that you’d like your own vehicle to have the same look, but what’s involved in converting your own headlights to HID? MotorFiend’s HID Headlight Conversion Guide is here to tell you exactly what’s involved.

You won’t need any special tools or anything more than basic automotive maintenance skills to install one of our HID headlight kits because they’re plug and play, meaning they come with everything you need to make the HID conversion a success.

Every HID headlight kit comes with two HID bulbs, two ballasts (which power the high voltage bulbs), wiring with connectors and mounting screws or brackets. MotorFiend offers you an upgrade to a slim ballast for and addition $14.99. The slim ballasts are smaller, lighter and made of plastic, rather than metal. They are newer technology, but have the same 35 watt output of the regular ballasts.

Your other option is express shipping. All of our HID products are shipped from California USA. Express shipping not only means it will be shipped by USPS as priority mail, but it will also bump your order to the front of our shipping queue.

Installation of your HID kit is simple enough. Don’t throw away your original bulbs though, just in case you ever want to switch back. When you open the kit be sure not touch the filament of the HID bulb with your bare fingers because the oils on your hands will reduce the life of the bulb.

Run the wiring out in your engine bay so you can get an idea of how the wiring fits together and you can also decide where to mount your ballasts.

The original wires that connect to the back of your headlight bulbs will join into the new HID wiring, so you’ll need to remove the plug from the back of the original bulbs first. Next connect the ballasts to the HID bulbs and locate the earth wires. Some kits also have a positive (red) wire that needs to be connected to the positive (+) terminal of your battery. Ensure you find a quality bare metal earth for the bulb earth wires. This may require the removal of some paint from your engine bay. If your HID bulbs are not correctly earthed they will not operate properly.

When you have connected all of the wires you should start your engine and switch on the headlights to ensure you have connected the kits properly. Ensure the wiring is clear of the fan belt before starting the engine. When all is working properly you can remove the covers from the HID bulbs, install them into the headlights and then mount the ballasts and wiring.
