Halogen headlamps are now most famous ones in the automobile industry. It is all due to their simplicity and low cost. Halogen bulb can last for 1000 hours in normal conditions. But with the lack of power, many of the people think twice before buying them.

Another problem with halogen is that it reacts to finger prints during installation. For example, when you are changing it you should not touch the glass panel because it will leave some oil on the glass resulting in the bulb heating up and dying sooner than normal.

Here are some pros and cons of it. Let's check them out.

High-intensity discharge (HID) headlamps are also known as Xenon lights. Which are mostly used for more result, due to its performance and the light it produces. BMW introduced xenon headlamps in the year of 1991 in their 7 Series.

Xenon lights work like a neon tube; they have full of gas with an electrode at both the ends and a current passing through it. In vehicles xenon is used as a mixture of tungsten and mix of gasses which gives the most effective result.

According to some research and data, xenon bulb makes 3000 lumens and 90mcd/m2 which is a very bright and powerful light.

The car industry has progressed a lot in the way of using LED headlights. With that, some parts of the car have remained the same while headlights have changed. Car manufacturer love LED lights because they save energy, give bright light, and can last forever (or at least many years).

The most powerful feature of LED headlamp is that they need very low power to function against its competitors. The first LED was implanted on Audi R8 in 2004, and it was very welcoming.

Their small size also permits producers to shape them into any of the models so no more to ugly-looking reflectors. And yes, good news; they also do not create heat like halogens or xenon lights.


  • Small in size
  • Less energy consumption
  • Last a long time
  • Very brighter


  • High cost to produce
  • Can be difficult to design, quality of different lights vary a lot
  • Can be more expensive

Brands like Audi and BMW are working hard to making new technology and make laser light to make happen, newer design and tech is 100 times better than LEDs.

As some car makers explained, their working style depends on three blue lasers which are sitting right after the headlight assembly, which blows into some mirrors which have yellow phosphorous gas, which helps the laser to produce enough light for the driver.

The very drawback of this laser headlamp is that they only work on high beam, which is very costly regarding price. "These laser headlights will add $1,500 to the M5’s price tag." (Credit - Wired.com)


  • Energy Efficient
  • Small is size
  • Very bright and far reaching light


  • Very expensive
  • They create a lot of heat; needs cooling

The owner must clean all his headlamps and lenses with a clean cloth as many times as possible to get a better result and to get rid of dust. If the lens is broken, then it should be replaced or fixed for the safety and efficency.

There are numbers of lights and lamps on a motor vehicle these days, which the driver needs to see the road ahead of him, to give the signal to other people and other vehicles too in the night. For safety purposes, it should be replaced if it goes out.

  • Day-time working lamps are optional in a car to make it more visible in the bright day too. These kinds of lamps are in trend nowadays. In many of the cars, we see DWLs. They should not be work with headlamps.
  • Fog lights are used in less visible conditions such as heavy rains, fog, smoke or dust storm. These lights generate wider flat beam from the bumper of the car to some distance so that driver gets the idea of the road he is driving on.
  • Fog lights should be able to work independently from the headlights; they can also be used with the parking lights with less brightness for others. They should not distract someone or disturb someone's eyes.
