Headlights are one of the most important components of any automobile; every driver realizes its importance and the usefulness as it’s not just a little something attached to the anterior end of the car. It’s more of a necessity that empowers the person to access the power of its sight and drive carefully after the sun sets down, because no matter how skilled of a driver a person is the skill needs a source of light to guide them through the ways for a happy and a safe strolling. Sure use of better headlights also gives the entire structure of a car a classy edge like the ones used in ludicrously expensive, luxurious cars but the bottom fact always lies in the importance of the purpose that it serves.
Following is a guide that serves two purposes:
(a) To help the buyer familiarize with the various types of headlights present in the market and their plus and minus points, their functions, so that the buyer could conclude by him as to which one suits them the best.
(b) it also sheds some light in the area of their installation, the lightning technologies making oneself efficient enough to bring about a change so minute on its own. You don’t need to run endless chores to a mechanic to do a basic job as this one for you.

What’s a headlight?
A headlight is also known by the name of “headlamp” that is fitted in the bonnet of the car to shed light on the way ahead after dusk or in any situation when there’s poor visibility say when there’s immense dense fog, cloudy rainy seasons etc. It hence enables one to see through things clearly and ensures a safe journey ahead. A factor that should be kept in mind while selecting them is that they should be of moderate intensity because a low intensity light wouldn’t provide proper illumination and a high intensity light could provide a string glare and hence temporary blindness to drivers coming from different side of the road.
The use of headlamps was first introduced during the late 1880’s, in its original form they were fueled by acetylene or oil. With advancement in technology with a gradual shift in era, electric headlights were introduced in 1898 by the Electrical Company of Hartford, Connecticut with the prime motive of providing the Columbia Electric car with an optional accessory.
Now to provide additional knowledge in consideration of the same, headlights constitute mere one part of the entire automotive lighting system of a vehicle like cars, truck, van etc others may include indicators, stop brake lights etc located at different places in a automobile.

Different Types of headlights:
All the headlights irrespective of their inbuilt features share the common function of being the source of illumination, what differentiates them from one another is the type of bulbs that they use to provide the light. Majorly there are three types of bulbs used in a headlight- halogen, xenon and LED.
Halogen Headlamps
Also known as tungsten halogen, it is an incandescent light that constitutes of small part of halogen along with iodine or bromine, together they create a combination of the halogen gas and tungsten that gives birth to halogen cycle re-depositing evaporated tungsten on above the filament, increasing its life and intensity. These are best if one needs a source of high luminous efficacy, working at higher temperatures.

Xenon Headlamps
These are a specialized type of lamp that discharges gas and electric lights that generates light on passage of electricity through ionized xenon gas at great pressure conditions. Final result obtained is a white light coming out of it very similar to the natural sunlight, one can call it to be the latter’s masquerading counterpart. The bulbs have their use in various fields such as in projectors used in movie theaters, torches, and of course headlights etc.

LED Headlamps
The abbreviation of “LED” stands for “Light Emitting Diode.” It is a semiconductor diode that emits light when voltage is applied to it, usually the quality of light depends upon the temperature, a low temperature results in a better source of light than at higher temperatures, and hence it kind of becomes mandatory to maintain a relatively stable temperature for a constant light output. The range of these lights are small, not too penetrating in nature, apart from headlights its used in abundance in manufacturing of Diwali lights as its miniature size help it to come in different shapes and sizes.

Which is Best to use : Halogen, Xenon, or LED Headlamps

This is a tough call, it actually depends on the consumer as to what are its needs and priorities and what kind of light suits him best in his interest. Following are few bullet points that’ll bring out the advantages and disadvantages of Halogen, Xenon and LED:
1. Halogen
• Perfect to use if one needs bright white light as the final output.
• It is durable and has a long lifespan.
• If damaged, the cost of replacement are highly reasonable.
• Too much of unnecessary heat is generated, loss of which means loss of energy for the entire system .
• It is highly reactive and hence rigorously mixes up when brought in contact with other substances.
• Needs to be handled with great precaution, inability to do so could lead to serious injuries.
2. Xenon
• Offers better illumination with much more clarity.
• Provides for better efficiency
• Consumes less power and hence is a little more cost effective.
• More durable than Halogen headlamps.

• Initial cost of investment is high. Not used in cheaper cars.
• Often come in high intensities that causes to much of glaring effect leaving the people coming from the other end partially blind for a few seconds, while driving this could lead to major accidents also it causes too much of a strain in the eyes of the other drivers.

3. LED
• It consumes to less of a power for an efficient, proper working.
• Energy consumption is low by LED lights. They can run on a low voltage.
• Available in small sizes, hence more versatile. Can be made available in the market in all shapes, designs and sizes.
• They are more expensive, mostly used in making of luxurious cars.
• It non-deliberately tends to produce extra heat that hampers both the quality of final light being produced and of course the loss of energy.
• More and extra efforts have to be made to maintain them at relatively constant temperatures, so as to obtain good lighting.
All in all, it is widely accepted that headlights in an automobile is as crucial as the engine itself. Its importance has been recognized by and large by every automobile manufacturing company. Limited by the budget constraint or the need restraint one can opt for any of the above lights by carefully weighing each of its pros and cons. The answer is not tough to decide. One just needs to have a clear mind with a clear insight as to what are they finally expecting.

So to answer the question which is best, all have advantage and disadvantage but hopefully this article will allow you to make a more informed choice.
