What is the function of the hole next to the fog lights on the Focus?

[DiEthan]

The hole next to the fog lights on the Focus is used to adjust the height of the fog lights. Fog lights have strong penetration and can make other vehicles notice and avoid them in low visibility environments. Taking the 2021 Focus as an example, its body dimensions are: length 4647mm, width 1810mm, height 1468mm, wheelbase 2705mm, minimum ground clearance 190mm, and body weight 1245kg. The 2021 Focus is equipped with a 1.5T turbocharged engine, with a maximum horsepower of 122PS, maximum torque of 153Nm, and maximum power of 90kW.
