The Best HID Conversion Kits

Most new cars feature halogen bulbs, and these generally are not too bright; they also seem to burn out somewhere close to 500 hours of use.

Lack of brightness and hours of use prompt more and more vehicle owners to go down the road of replacing their factory lights with HID conversion kits. 

Alternatively, high-intensity discharge (HID) bulbs will survive up to 8000 hours of use. So, of course, it makes perfect sense to want to switch out your factory lights. If you get better visibility on dark roads, making them safer and a lot longer hours of use, then why not.

Even though it makes a lot of sense to switch them, how will you go about getting it done? You could go back to the dealership, but as with anything you do at a dealership, it can cost an arm and a leg. Or, you could opt to do it yourself. It’s not a difficult or time-consuming job, but then that’s not the problem; the genuine concern is choosing the best HID conversion kit.

The Best HID Conversion Kits-What To Look For 


Kits are available with 35W and 55W. There’s nothing wrong with the quality of either, but there are advantages and disadvantages with both.

You’ll read that 35W is about three times brighter than the factory halogens on most cars, whereas 55W are brighter still. But having such high wattage puts a strain on your car’s wiring and battery. 35W creates a lot less heat and is kinder to the car’s wiring.

You also have to consider the legal limit of the headlight’s brightness.


Try to choose the conversion kits that have AC power. DC supply will test your wiring, but they will probably be a little bit cheaper to buy. AC supply tends to keep the light more stable as well.

Benefits of the Best HID Conversion Kits

Brighter light

HID bulbs produce a brighter light than both halogens and LEDs. Bright white lights are best if you drive at night over a longer distance because the light tends to be closer to daylight. But if you’re driving in rain or fog frequently, you might be better choosing a more yellow tone of light from your HID kit.

Lower power consumption

The typical set of halogen headlights use in the region of 15 amps continually, whereas HID lights use up to 20 amps on first putting them on; this drops down to about three amps in continual use.

Longer life

Traditional halogen bulbs use a tungsten filament and halogen gas. As the gas gets hotter, it illuminates the bulb. However, in HID bulbs, electrodes charge the Xenon gas to light up the bulb.

An average halogen bulb will last between 500 and 1000 hours because the filament will no longer work. Using Xenon gas allows an HID bulb 2000 to 3000 hours of use.

Color Options

HID conversion kits typically offer seven different color options, whereas halogen bulbs come in one color and LEDs a choice of four.
