The Role of Fog Lights in Your Car

When we need to drive in the early morning, the beautiful white embracing of nature, that we call fog, does make the ambience dreamy but at the same time makes driving immensely difficult. Mere usage of full beam headlights doesn’t really help. Driving gets slower and trickier till the fog is clear. But when you are in a hurry, and are in a daily commute, waiting for the fogs to get cleared isn’t an option. For this, the latest cars are having Fog lights that are specifically engineered to deal with such conditions. Today, it is also held as one of the major safety features that have outshined the advantages of even highly powerful headlights. So what exactly these fog lights do? How do they execute their roles in the modern cars? When we asked this question to one of the experienced staff of the Union Park Hyundai dealer, he explained us the science that works behind these fog lights.

How the Fog Lights Work

The term “fog lights” though has its focus mainly on addressing the fog issue, it actually is made to work for every driving condition that results into poor visibility. Apart from fog, these lights also work with snow, mist, and even blows of sand.

The reason why fog lights work better than headlights is that they are placed in much lower line than the headlights like near the lower bumper cover, that doesn’t allow any element to interfere between the rays of light hitting the ground. The fog lights typically will have a sharp cutoff angle especially at the top of their housing. This is don so that none of the beams should shine up enough that can reflect off the fog but should only illuminate the road lying ahead. When angled downwards, these fog lights won’t get the “reach” that we get in headlights, but they are capable enough to light up the road ahead especially for the drivers. This helps them to slowly make out their way and drive towards their destination.

The other benefit of the fog lights is that since these lights don’t reflect the light back, drivers from the opposite side become more aware of the presence of your car, while not being blinded by the brightness of the fog lights.

Differentiating Driving Lights and Fog Lights

“Driving lights” in real sense of the term is quite vague. In literal sense it can include any car light that helps in driving. It could be the headlights or any other auxiliary lights, which should also include the fog lights or turn signals. But in the industry, like many other terms, this term is being referred  to those additional large circular lights that are placed up front, that are usually seen on rally cars or other big off-road vehicles.

As explained to us at the Union Park Hyundai dealership experts, fog lights on the other hand differ from these driving lights in its very internal construction and also in its placement. The purpose of both these kinds of lights differ too. While headlights and turn signals are dedicated to illuminate the road ahead when it is dark, and to signal other drivers about its upcoming turn, fog lights are to disburse the natural elements like fog, mist, snow, sand and make way for the light beam to reach the road, in order to increase driving visibility.
