Yellow Vs. White Fog Lights: Makes A Better Decision for Your Car

When driving, visibility is one of the aspects you have to keep up for your safety and other road users. However, there are some natural conditions that you may encounter on the road that can affect your sense of sight, for example, fog. Fog causes cloudiness on the road ahead and makes it hard to navigate. To deal with the issue, fog lights have your back to keep your visibility intact in poor conditions. Talking about headlights, there is the yellow vs. white fog lights debate that you should know as an experienced mechanic.

Yellow or white refers to the color of the beam that comes from the fog lamp. There is a looming argument on which of the two is the best. With our experience in auto-mechanics and general repairs, we will guide you on the concept of the fog lights and touch on the yellow and white lights to give you a better understanding.

What Are Fog Lights and Their Purpose?

Fog Lights

Fog lights are among the many car light types that boost visibility when driving. There is a debate about their importance among auto enthusiasts, as their use is rare. However, despite their rarity in use, they are essential in situations where there is poor visibility due to certain environmental factors. These factors may be fog, mist, dust, and sandstorms, which getting your way through may be a problem due to the thick cloud they create. What about the headlights? You may ask. The headlights can function in such situations, though there is the issue of the lights refracting and hitting back to the car.

Here is where the fog lights come to play as they have a bar-shaped beam, and their position allows them to target the ground at a sharp angle. This operation manner prevents the light from reflecting off the mist and upholds visibility in such difficult conditions. The fog lamps are usually low set, below the headlights, to achieve their purpose of lighting up in foggy or dusty conditions. In some vehicles, they play a role in upholding their looks and bringing the shape of the frontal bumper.

The sharpness of the fog lights also helps notify other road users of your presence on the road. In such cloudy conditions, visibility is low, especially if it is at night. The headlights may not be strong enough to alert oncoming road users that you are on the road, and it might cause an accident. One thing to understand about this type of light is that they have a lower reach compared to headlights, but they provide decent light to illuminate the road ahead.

On the light types, as a mechanic, you understand it is all about temperatures, with the unit of measurement being degrees Kelvin. The lower the value, the warmer the color, with yellow being somewhere around 2000-3000 kelvins, while the intense colors, white in this case, ranks at around 6000 kelvins. Let us have an in-depth look at these types of fog lights.

Yellow Fog Lights

Yellow Fog Lights

As its name hints, the yellow fog light takes on a yellow or amber coloration when lit. You can notice the lamp’s color, where some models have white light, but the lens has a yellow tint. This type of fog light is one of the most common, with many preferring it as the human eye is more tolerant to yellow lights. The human eye processes light colors differently, and it seems more accommodating to yellow lights.

The primary purpose of using yellow in fog lights and other frontal car lights generally is to improve visibility, first of all, due to its brightness and also because it’s friendly to the eye. They are sometimes referred to as amber fog lights as the color is closer to amber, primarily when looking at the lamp and lens. This fog light comes in handy in snowy situations, allowing for optimum visualization, even in snowstorms and rain.

There are two ways to get yellow fog lights on a vehicle. The standard method is using a cover, which is very flexible and works according to your preference. You simply attach an amber-colored cover to a white fog light, and the lights will take on this color when lit. If you do not want the yellow light, you simply remove the cover. The other way is by getting yellow LED bulbs, which are getting popular in the autotuning and maintenance scene.

One of the yellow light pros is that they have a longer wavelength, which does away with refraction, reducing glare and light bouncing back to you. There are several brands of yellow fog lights on the market, such as Samlight Fog Lights, which are of high quality and have durable body. You can use it for off-road engagements, on your motorcycle, boat, and in other areas, which shows you how versatile it is.

From the same manufacturer, there is Samlight LED Light Bar, which is also excellent for lighting up dark and cloudy areas. They have a sturdy build that makes them durable, and they come with mounting brackets for convenience during installation.

The White Light

White Fog Lights

On the other side of the argument, we have white fog lights, which are also standard in car tuning. As earlier hinted, the light has a temperature of around 6000 kelvins. A definitive characteristic of the white light that you will notice is that it has a white appearance, sometimes almost having a bluish hue. The white light is ideal for everyday lighting purposes, where you can use it as an additional white source when driving. However, like a fog light, it is not as effective as the yellow light as it has a shorter wavelength. A short wavelength will cause refraction, and the light might bounce back.

The good thing with this light is that it is bright and will indicate your presence to other road users in foggy conditions. The white fog lights are also excellent aesthetic boosters, which you can light up during the day to make a statement.

Among the notable white light brands in the market are the Nilight LED Pods, which you can use in multiple settings like your off-road car, boat, and many more. It uses high-quality LED chips, which produce a concentrated beam for long distances. If you have white lights and you prefer amber, you can get a cover with the desired color, which you fix and remove as you like.

What Is the Difference Between Yellow and White Lights?

Yellow Vs. White Fog Lights

If you want to understand these two fog light varieties, you need to understand their differences. The significant variation is the different colors, with them having colors as indicated in their names. The color difference comes due to their different temperatures. To understand how the two contrast, you can check the light temperature chart, which goes from 1000 kelvins on the lower side to 10000 kelvins on the highest value. The yellow light is around 2000 or 3000 kelvins, while the white light is on the 5000 to 6000 value and mostly uses HID or LED bulbs; hence its intensity.

The brightness of the two lights is another distinction point, where the white light is brighter than the other. The shine makes it less friendly to the human eye, which will perfectly accommodate yellow illumination. When it comes to use on the road, the yellow light is preferable as it has a longer wavelength, meaning it will brighten the path ahead for longer distances. It does not refract, which ensures no glare hits you.
