What Are HID Headlight Conversion Kits And How To Buy One?

HID means High-Intensity Discharge. The HID headlight was first introduced in the 90s and initially made to be used exclusively by luxury cars. This type of headlight works in a way similar to a fluorescent bulb. But instead of using incandescent or halogen, vehicles with HID lights get to use xenon bulbs. This provides more illumination on the road than a standard halogen headlight. Some kits may deliver up to 100% illumination compared to a regular bulb. In addition to this impressive illumination power, HID headlights can also be installed in a variety of customized colors that add beauty and uniqueness to your car.

Types of HID conversion kit.

There are five types of HID conversion kits, namely, H1, H2, H3, H4, and H7. What distinguishes these conversion kits from each other is their Monofilament. Monofilament determines the beam of a conversion kit- the longer the monofilament, the higher the beam to be produced. H1 kit is a foot-long monofilament and is used in fog lamps. Most cars produced in japan comes with an H3 kit. The H4 is a 3-foot double wire bulb, commonly used on bikes. H7 kit is also a 3-foot kit used in fog lamps.

Buying guide for a good quality conversion kit.

Do you want to change the halogen light of your vehicle to a high-intensity discharge? Or you want a better conversion kit for your car? Here are some important tips or features to consider when next you are shopping to buy a conversion kit. 

Brightness: the brightness level of a headlight is determined by the lumen. It is the first factor that should be considered if you want to get the best HID headlights. Understanding how to choose the right kit based on the lumen might be complex because the HID kit naturally tends to be brighter than the halogen bulb. Bear it in mind that the intensity of a bulb doesn’t determine the level of brightness. Many manufacturers or brands will advertise how bright their HID light is compared to a halogen light, but don’t be fooled by that. The real test of brightness for the HID conversion kit is the number of lumens written on the kit package. In case you find a bulb with a high lumen, you can be sure that you are looking at a very bright headlight. Intensity and lumen are entirely different features. A bulb can have high intensity and low lumen such a headlight will not be bright. Click here for a detailed comparison between HID and LED headlights. 

Bulb power: this refers to the wattage of the bulb. It is the electrical power of the bulb- the higher the watt, the higher the energy consumed by the bulb. For you not to run down your vehicle battery within a short time frame, it is better to get a conversion kit with lower wattage. A low wattage bulb will consume less energy. HID headlight kit comes with 35w or 55w bulbs. They both have their specific advantages and downsides. Although the 35W bulbs are less powerful compared to the 55W option, they are still much more powerful than halogen lamps. They are also less likely to affect your vehicle wiring and are easy on the battery. However, if you prefer more power and brightness over these factors, then the 55W model is the better alternative.

Color/temperature: this is measured in kelvins (K). The reason for making the color a factor to consider is because not all colors are considered legal in various cities. For instance, only racing cars are permitted to use white headlights in the US. Therefore, if you are not buying an HID kit for a racing car, you should go for another color apart from white. Just ensure that you check for colors that are considered legal in your area.

Durability: this cannot be overemphasized. Durability should be ensured when choosing a conversion kit. HID headlight conversion kit that comes with 55W bulbs are strong, but they consume more energy and generate heat. This not only affects their lifespan but may affect that of your car battery as well. 35W bulbs, on the other hand, consume less energy and produce less heat. On the average, a 35W HID headlight conversion kit lasts longer than the 55W. The choice is yours to make.


Even after learning all these important tips, there are still plenty of things to do to ensure that you only purchase top quality conversion kits. Talk to others who have done the same and read reviews to get public opinion about any product you are considering before making a purchase. This will save you time and money in the long run.

The F-TYPE Coupe visual message is defined by three key ‘heart lines’, that visual message beginning with the formidable grille. It is from the twin ‘shark gill’ openings that sit either side of the grille that the essential first heart line – which mirrors the design of the F-TYPE Convertible – flows and begins to take shape. Running up through the headlamp, and accentuated by the LED ‘J blade’ signature running lamps, the line then arcs up over the front wheel arch before dropping elegantly as it runs through the door, washing out into the muscular rear haunch.

The second heart line begins at the rear edge of the door, swelling outwards and upwards to create a visually strong wheel arch, emphasizing the car’s rear-wheel drive layout, before dropping vertically through the tail lamp ...
