We all love to drive. Yes, you too. Because you are reading this article means you are also a car enthusiast. Well, we love cars but do we really understand or even know our cars in detail? Do we know the small but important parts such as tyres and their types, brakes, clutch, how power generates, horns, and especially the headlamps or headlights? Here, in this article, we will discuss car headlights and will get to know the different types and usages of them.

If you are driving on a dark and dingy road, the car headlights become the most important part especially from your safety point of view. The history of car headlights is long starting from the carbide lamps to the modern laser lights. But we still are juggling with some of the jargon in this industry like Halogens, LEDs, Xenon, Projectors, etc. So, let’s check them out.

Halogen

Basically halogen lights or bulbs are quite similar to the normal electric bulb. The only difference is, in the electric bulb, the thin/short filament gets heated to emit light. But in the case of halogen, the light emits with the use of halogen gas.

The halogen lights are the most widely used car headlights even though the light is not well bright. It emits a kind of yellowish light and ranges around 100 meters. Because most of the energy gets wasted in heating the filament and not in producing light.

LEDs

These are the most energy-efficient car lighting system. The LED stands for, Light Emitting Diodes. The whole mechanism is quite simple and takes very little or almost no time. Here no extra energy gets wasted in heating. The electricity flows in the diodes and light emits.

Since they are quick and cover a large distance, they are being used in daytime running lights and tail lights. These LEDs can be used as low beams as well as high beams depending upon the choice and requirement.

Xenon

These are also known as HID (High-Intensity Discharge). The xenon lights are almost similar to the tube lights. Here, the xenon gas gets electrically charged and produces light. But the produced light is slightly bluish in nature but gets mixed up well with the natural sunlight.

The xenon lights are slightly expensive than the halogen lights but they are the value for money choices. The lifetime or the durability is much more than the halogen lights. The xenon car headlights take some time to reach their maximum brightness because they take a little time to heat up. That’s why most of the cars have an extra halogen light.

Projectors

This is nothing but an arrangement of a lens that makes the light focus on the road. It can be understood y taking the example like, watching a movie on the projector or showcasing any ppt presentation.

Laser

Laser lights are the most advanced lights available in the market right now. With the help of a laser, the lights energize a gas and the gas glows extremely brightly. The range is quite large and better than any other type of car headlight. The laser can make the driver see up to 600 meters. These are the best ones but the cost is also equally higher than any other type of car headlight.

How many headlights are legal front in cars?

One is enough. But in some cases, it can be 2 to 3 headlights.
