Projector Vs HID Headlights: What is The Difference?

As an owner of a vehicle, it is normal to be curious about different headlight terms and types. Many of us already know that most vehicles come with a stock headlight that is halogen in reflector housing.

But you may keep hearing about terms like HID and projector headlights. If you want to install them on your vehicle, you may need to replace the headlight housing. It is unless the car already comes with a stock projector housing.

If these terms are unbeknownst to you and you want to know their differences, you are in the right place. Go through the sections below for proper details about projector and HID headlights.

Projector Vs HID Headlights Comparison Chart

The comparison chart below should provide you with basic and brief explanations of projector and HID headlights and why they are different.

As you can see, the main difference between the two is that they are entirely two different parts of a headlight system. A projector is the housing, while HID is a bulb.

What Are Projector Headlights?

A projector headlight is a complete headlight housing that even includes the bulb. In fact, HID is the bulb that works the best with a projector housing. It is bright, pricey, and slowly becoming more popular.

Similar to another headlight system, reflector, projector headlights also have a reflector bowl. It has a unique shutter that helps the headlight focus downward. The components below are what completes a projector headlight-


The bulb is the root source of the light. A projector headlight is best compatible with HID bulbs. But it also works with LED. Since LED and HID have a high lumen, projector headlights are brighter than reflector headlights that use halogen.

Reflector Hood

The elliptical shape of the reflector in a projector headlight makes them different from a reflector bowl in a reflector headlight. This shape allows the light to focus solely on one point, which is the shutter.


With the help of the shutter, the light coming from the reflector gets cut off by half. It then goes downward only. As a result, projector headlights have good downward visibility.


While the light coming from the shutter reaches the lens, it spreads evenly on the road. Projector headlights have pretty modern lenses because of their high usage on luxurious cars in the early days.

Why and Who Should Use

Projector headlights are the brightest ones you can go for. Keep in mind that projector housing accepts HID bulbs the best. For LED or halogen users, projector headlights wouldn’t be an ideal investment.

On the other hand, projector headlight systems are pretty expensive. It has two reasons. They have a higher production cost and provide brighter light. So, consider your budget and make the right decision.

Finally, projector headlights are suitable for nighttime drives. If driving at night is something you need to do, we suggest going for projector housing.


  • Projector headlights are brighter than reflector headlights.
  • They provide better downward visibility for the avoidance of blinding others.
  • They look stylish.
  • Projector headlights reduce the dark spot issue.


  • It cost so much, which can be an issue for many.
  • Projector headlights take more space to install.

This excellent projector headlight survived salt spray, moisture, and dust test and operated perfectly on a wide temperature range. Aside from all that, you are getting a complete headlight that looks so modern.

What Are HID Headlights?

HID headlights are one among three types of headlight bulbs. HID is brighter than halogen but less bright than LED. It uses a ballast system to regulate and transfer electricity to the bulb to avoid wasting energy and reduce burnout possibilities.

HID bulbs usually last for around 2000 to 3000h and provide enough light to let you traverse through the darkness of the night. Have a look at the components of an HID headlight system-


The bulb contains two electrodes inside it. By jumping between them, the electricity arcs create light. Meanwhile, there are metal halide salts with xenon gas inside an HID bulb. This gas allows the light to brighten up as quickly as within ten seconds.


The reflector reflects the light from the HID bulb and projects them on a shutter. This reflector is elliptical shaped because it is required to use projector housing with an HID.


The ballast transfer and regulate the electrical energy needed for the light bulb. The ballast doesn’t allow the light to spend more energy than necessary, reducing wastes to a high amount.

Why and Who Should Use

HID headlights are a good option for people who wants to upgrade their stock headlights. It is a bit pricey compared to halogen lights.

Meanwhile, if you have a stock halogen headlight, you may need to change the entire housing to projector, which will cost extra. It may cost a total of $275 on average to do a total housing change along with the bulb. Consider these expenses before going for an HID.

HID allows you to drive properly at night and offer you a high lumen and color. If you need to commute at night pretty often, HID headlights are an ideal option for you. Their installation process is complex most of the time and requires expert helps. So, consider that as well.


  • It provides an excellent downward focus.
  • It gives you a bright light beam with a whiter color.
  • It lasts longer compared to halogen headlights.
  • HID headlights are really energy efficient.


  • They are pricier compared to halogen headlights with reflector housing.
  • They have a lower brightness than LED lights.
  • The installation process of HID lights is often very complex and time-consuming.
