Why do we use fog lights and why only yellow is chosen most of the time?

What are fog lights?

Fog lights are those extra lights which are switched on during the foggy or misty conditions only. These lights are generally mounted on the upper surface of the vehicle or at the lower body parts below the normal headlights. They are available in various colours and intensities. The colours and intensities are determined according to the density of the mists. Anyway almost all vehicles have them virtually. Their assistance can be important in poor weathers.

How they work?

Most of us might have seen the fog lightsto be yellow, because by tradition the lights are yellow. The reason is a scientific demand. It is scientifically proved that the colour that could penetrate to the fogs or the mists have to be single colour. Depending upon the geographical area under consideration, only one type of mist or fog would appear, and hence one colour would be enough to penetrate through them. Now question arises what would happen if other colours are used in the headlights? The answer is simple. It's all about the frequency and the corresponding wavelength. Every colour has its own frequency range and when it is applied on a material which would not allow it to penetrate then simply the light would scatter in all directions. Which results in blurring effect o f the lights? Water vapour and dusts provide the major surface for scattering.

Other alternative colours:

People suggest trying red fog lightssome time. But the scientific answer to the demand is that it can pass to long distances because of its wavelength. But it doesn't mean that it can be used in nights with foggy roads. It will simply cause connotations to drivers. Red is used to stop the vehicles by default. So driving would be a bit more uncomfortable. Hence, yellow becomes the next most suitable choice. Another reason for choosing the yellow fog light is that it has the second longest wavelength in the visible region of light spectrum.

The entire discussion done above about the selection of colours has a relation with the size of the water molecules. It sounds a bit plausible and scientific. The wavelength of the lights becomes irrelevant when molecules of water vapour are large enough. The larger water molecules don't put contribution in dispersion. Previously, car companies used to assume that using yellow lights could possibly minimize the blurring effect to the minimum. They were not aware of the fact that the size of the water molecules has something to do with the light dispersion.

This is the reason why yellow lights and yellow signals are used to slow the speed of the vehicles and to look for the obstacles.

The LED Fog Lights- New Innovations

Fog lights form a very important part of the car's defenses against the extremes of weather. Most car fog lights are able to penetrate through the mists and fogs on the roads and highways. So, it is important for the fog lightsto function well. One of the new innovations in the field of lightings is the LED technology. Since this technology does not pollute, it is safe and environment friendly. So, now we will focus on the many benefits of LED fog lights. These lights deliver the same benefits as any regular LED bulbs and lights.

LED lights are considered to be as alternatives to the conventional options like halogen bulbs and incandescent bulbs. This is because LED lights use better technology. This technology does not pollute the nature. Moreover, LED fog lights are more inexpensive than the regular fog lights. At the cheap prices, the LED lights are offering the same kind of efficiency which is provided by conventional fog lights. The power consumption is almost nil. Thus, you won't have to worry about your light being overheated and damaged by heat. The LED fog lights won't actually become hot with their use.

These are only the economic benefits of LED lights. However, we should check out the main benefits. The LED light of these car bulbs remains to be an edge over the regular halogen-powered fog lights. The old fashioned lights emit powerful light. However, with time and wear and tear, the halogen fog lights may produce inconsistent light. This will not happen with the new LED fog lights. The light will be uniform and consistently bright at all situations. The light bulbs are made so as to last for long. Thus, these fog lights have durability and strength.

Economically, the Fog lights are really beneficial. They help the car users to enjoy convenience and efficiency. Most halogen lights do not last long. They end up polluting the environment. Also, some of the emitted light is too harsh on the eyes. Thus, the LED lights are a lot easy on the eyes. They also do not produce any polluting gases and chemicals. They function well in almost all kinds of problems and climactic extremes. Therefore, it is important that we also warm up to such virtues and get more LED lights for our cars. It will be really wise.

Fog light bulbs: They are the protectors during low visibility

If you think you have headlights installed in your car and you do not need fog lights then you are wrong. Although the usage of both is same, that is to improve visibility on road. But the reason you need fog lights for your car is that they are designed to provide you better visibility during poor visibility as compared to headlights due to their greater capacity to penetrate especially in conditions like fog.

Fog light bulbs have greater intensity and hence the light they emit is brighter than headlights. They are usually mounted below headlights on the front of the car. The light they emit provides better vision for the driver to drive during fog when it is extremely difficult to drive and chances of collision and accidents are high.

To keep them functioning is the prime responsibility for the driver for safe driving. Both head light bulbs and fog lights can be easily replaced using replacement headlight bulbs. The aftermarket is offering various types of light bulbs like halogen bulbs, led bulbs, HID Bulbs. All of them have their own advantages to offer.

Halogen bulbs: they are created using tungsten filaments and emit bright light. As electricity passes the filament the light is produced.

Led bulbs: these bulbs emit brighter light than halogen bulbs and are available at lower costs. Their brighter light makes it really convenient to drive through fog, bad weather, dark alleys etc.

HID bulbs: These High Intensity Discharge bulbs are extremely high on providing bright lights. Usually such bulbs use Xenon, neon gases. They consume less electricity and therefore they are fuel efficient and leads to cost saving in long run. Another great feature is their availability in various bright colours and attractive shapes.

You can select anyone you find appropriate for your car. Fog lights are also considered as an accessory for the appearance of the car. That is one reason people do not feel their need. But their functionality is important for the proper functioning of car. They not only make your car look good but also help in their functioning for long time.

Before getting fog lights, make sure you know what you want. Usually these lights are made to suit all types of cars, but sometimes some of them may not be apt for your vehicle. So take the advice of an expert for the best buy and appropriate installation.

Fog lights are must for safe driving. They are the reason people can drive even in impossible conditions like rain, storms, etc and they add the vision with style making you car dazzle in dark. Improve your vision with correct fog light bulbs and enjoy a drive which is safe and pleasurable.
