Yellow Vs. White Fog Lights: Which Are Better?

While driving a car, visibility is one aspect to consider for your safety and the safety of other road users.

You may encounter natural environmental conditions that can disrupt your vision on the road, such as fog. Fog can cause cloudiness on your way, thereby making navigation difficult. Driving carefully, using the wipers, and paying full attention to the road may no longer be enough. You need the correct type of fog light to tackle the problem.

These days, there is a debate about yellow fog lights versus white fog lights, which might interest you.


You can be a decent driver and owner of a vehicle, yet you might not have insight into these sorts of vehicle lights. Some people may mistake these car lights for headlights, as many of these lights are mounted on the front of a car and work to provide illumination to the driver in poor visibility conditions. However, fog lights differ from headlights in both function and form.

Fog lights are usually placed under the headlights, but some car models have them mounted on their bumpers. They by and large discharge yellow light, which has the most imperative infiltration capacity among every single colored light. This helps the driver to have much better visibility on foggy days. You can also find others that produce white light. White light from bulbs can sometimes cause glare in the eyes of approaching road users.


Yellow Vs. White Fog Lights Differences: Detailed Analysis

As the name implies, the yellow fog light takes on a yellow color when turned on. This kind of fog light is perhaps the most widely recognized; many incline toward them because the natural eye is more lenient toward yellow lights. It enhances a car’s aesthetic appearance, and users can turn it on to make a statement. Then again, a complete component of the white light is that it has a white appearance, nearly with a somewhat blue shade. It is popular with many car owners because it brings certain simplicity.

Bulb Compatibility
There are no significant differences between yellow and white fog lights in bulb compatibility, as both can work with halogen or LED bulbs. Putting HID in the fog lights is not advisable. When people drive at night, HID lights provide them with more light to see, especially in the area immediately in front of the vehicle. In theory, this could make HID lights safer for the driver, but in the real sense, it could cause more danger because the solid blue light they emit can blind other road users.

Color Temperature
The color of the yellow and white lights differs because of their different temperatures. By looking at the light color temperature chart, you can see that yellow light functions around 2,000-3,000 kelvins, while the white fog light is between 5,000 and 6,000 kelvins.

The yellow fog light reduces glare towards other drivers. This is particularly significant during rain, snow, or fog, or anytime water is in the air reflecting light towards you. That is why the yellow light used to be the more common fog light. However, the white fog light enlightens the street better due to its brightness than the yellow one.

The yellow fog light illuminates the path ahead at a greater distance because it has a longer wavelength. Unlike the yellow fog light, the white fog light is less effective due to its shorter wavelength causing it to refract or bounce backlight.

The white fog light produces more glare when compared to the yellow fog, which has no glare.

Are Yellow or White Fog Lights Illegal?

This is a great question to consider depending on your location or where you plan to visit. Various domains may have explicit laws concerning the utilization of these car lights. For example, in Florida, traffic laws prohibit fog lights when other vehicles are on the road unless there is fog.
