Drivers are just realizing there's a hidden button in their cars which can help them see better and stay on the road

DRIVERS have realized a hidden button in their vehicles can help their vision on the road and keep them safe while behind the wheel.

When weather conditions call for a bit of fog, many drivers can use a common feature to help see through the mist.

Front lights aren't a legal requirement, but most car manufacturers include them on their vehicles nowadays, per Warranty Direct.

Some are automatically activated, while others require a button to get them to appear when the driving situation calls for it.

The front fog lights are placed "low in the bumper and produce a wide, flat beam," according to Driving Tests.

The main difference between fog lights and full-beam headlights is that they don't reflect off of the fog.

Additionally, the low placement offers a method of cutting through the fog and lighting up the road below.

If drivers struggle to find the button, they should look by their lower right knee, as it could be placed on the dash with a symbol that represents a headlight and a vertical line cutting through three horizontal lines.

Otherwise, if the button isn't by a driver's right knee, they should look to the left of the steering wheel where the windshield wiper and high-beam light controls are.

There may be a button there with the same symbol that activates the fog lights.

Luxury cars and high-end models will again likely have automatic fog lights.

To make sure, it's best to check the owner's manual.

Another hidden button that can also improve vision while driving is the rear demister.

It de-fogs the rear window so drivers can see traffic following behind them.

Although it's different than the front demister because it uses wires to heat the window for evaporation of condensation instead of air vents, per Driving Tests.

The button should be located near the air conditioning controls on the dash and has a rectangular shape with three arrows.

As The U.S. Sun previously reported, the rearview mirror can also assist with vision while driving with another button.

Some cars have a special button that will dim the mirror to reduce headlight glare - which can be extremely useful when driving at night.

A small button that looks like a power button can be found in some cars on the bottom of the rearview mirror.

The feature makes driving at night safer, per the SEAT website.

The brand revealed: "The auto-dimming rearview mirror offers greater safety when driving at night, as it stops you from being dazzled by traffic traveling behind."

"It consists of a mirror element and an electronic system that detects light from in front and behind by means of photo sensors. If the amount of light from behind is greater than that in front, the mirror is darkened."
