How do projector headlights work – Ultimate Guide

Projector headlights are car headlights that use a projector lens to cast a beam of light onto a flat surface. The light is then reflected off that surface and into the eyes of oncoming drivers, providing them with more illumination than traditional headlights.

How do projector headlights work?

Projector headlights use a lamp with an elliptical reflector to project light through either a clear or frosted lens, sometimes referred to as the cutoff shield.

The projector lens magnifies the beam of light produced by this lamp and projects it onto a flat surface for better illumination, like the street in front of you.

The light projected by the projector lens is then reflected off of this surface and into the eyes of oncoming drivers, providing them with more illumination than traditional headlights. This increased level of illumination can help to improve safety while driving at night.

Projector headlights have become increasingly popular in recent years, as they offer some benefits over standard headlights, such as:

  • A broader and longer beam of light.
  • Better visibility and less glare for oncoming drivers.
  • Sharper cutoff than traditional headlights; this makes them popular with enthusiasts who enjoy modified cars that can be identified by the “wall” or area of darkness above the LED taillights.

Types of Projector Headlight

There are two main types of projector headlight bulbs: halogen and LED.

Halogen projector headlights use a standard halogen bulb, the most common type of light bulb. These headlights provide good visibility and a wide beam pattern, making them popular for drivers.

LED projector headlights use an LED bulb, a light bulb that uses light-emitting diodes (LEDs) to produce light. LED headlights are becoming more and more popular as they offer several benefits over halogen headlights, including:

  • A longer lifespan – LED bulbs can last up to 50,000 hours, compared to 1,000 hours for halogen bulbs.
  • Less power consumption – LED headlights use up to 80% less power than halogen headlights.
  • Greater brightness – LED headlights are up to five times brighter than halogen headlights.
  • Cooler operating temperature – LED headlights run cooler than halogen headlights, which can cause problems with traditional headlight housings.

Projector Headlights vs. Halogen Headlights

There are several factors to consider when choosing between projector headlights and halogen headlights, such as:

  • Price – projector headlights tend to be more expensive than halogen headlights.
  • Level of brightness – LED headlights are typically brighter than halogen headlights.
  • Size of the projector lens – projector headlights typically have a larger or longer projecting lens than halogen headlights.

Projector Headlights vs. LED Headlights

There are also many factors to consider when choosing between projector headlights and HID/LED headlights, including:

  • Lifetime – HID/LED lights typically have a longer lifespan than projector headlights.
  • Power consumption – projector headlights consume more power than HID/LED headlights.
  • Size of the projector lens – projector headlights typically have a larger or longer projecting lens than HID/LED headlights.
  • Price – projector headlights tend to be more expensive than HID/LED headlights.
  • Level of brightness – LED headlights are typically brighter than projector headlights.

Which type of headlight is right for you?

Ultimately, deciding which type of headlight is right for you comes down to personal preference. If you are looking for a brighter light with a longer lifespan, LED headlights may be the right choice.

If you are looking for a good blend of price and performance, then projector headlights may be a better option.

Conclusion:

Projector headlights have become a popular choice for drivers in recent years, as they offer several benefits over traditional halogen headlights.

These headlights provide a broader and longer light beam, making them ideal for night driving. They also produce less glare for oncoming drivers and have a sharper cutoff than traditional headlights.

FAQs

Are our projector headlights legal?

It depends on the state/country you live in. In most states, projector headlights are legal as long as they don’t exceed a certain level of brightness (usually measured in ” lumens”). Be sure to check your local laws before purchasing any new headlight types or upgrades that may not be street-legal.

How do I install projector headlights?

Projector headlights typically do not require any particular installation. Most projector headlights are plug-and-play with the car’s factory wiring, meaning they will work immediately without any modification to its existing electrical system.

A few models may come with extra wiring for advanced circuits that can be connected to your vehicle’s headlight circuit.

What kind of bulb goes in a projector headlight?

Projector headlights use various bulbs, including halogen, LED, and HID/LED. It is essential to check the specifications of your specific projector headlight before purchasing a replacement bulb. Most projector headlights use an “H” or “HS” type bulb.

How much brighter are LED headlights than projector headlights?

LED headlights are typically up to 5 times brighter than projector headlights. This increased brightness can be helpful for drivers who need a lot of light while driving at night. LED headlights also have a much longer lifespan than projector headlights.
