Fog is made up of tiny water drops or ice particles that function like little mirrors, scattering or reflecting light. Therefore, if you are driving in fog with your headlights on, a lot of light is reflected back towards you, which can cause a significant reduction in visibility. To avoid this kind of dangerous situation, fog lights are helpful. It is important to remember, however, that in addition to selecting the correct beam for the fog lights, it is also necessary to fit them correctly - in the right positions and at the right height.
The purpose of fog lights is to directly illuminate the road surface in front of the driver, in order to help him or her drive safely through the fog zone. So, what is the correct mounting position for fog lights on the vehicle bumper? What is the correct fog light beam?
Fog lights have a particular beam pattern that is wide and flat. A high-quality flat beam must have a clear chiaroscuro border to minimise possible reflections that could dazzle the driver. In order for the fog lamp to fulfil its purpose, the beam must get through the fog and illuminate the road surface to enable the driver to keep the car in its lane.

With regard to the appropriate mounting height, this should be a minimum of 250mm above the ground, but no more than 800mm. The fog light must also not be mounted higher than the dipped beam headlights.
Therefore, whether you choose a yellow light or a white light for your fog lights, the most important factor that will determine their correct functioning is the correct light beam and their correct mounting position. In this way, fog lights will be very helpful in improving the illumination of the road in case of fog, snowfall or heavy rain.
