Fog lights, Everything You Need to Know
The law stipulates that fog lights must be included in the rear lights of a car, while the front fog lights are a useful extra that car makers can use to lure buyers towards higher spec models. A basic part and an optional part. But fog lights are an element of the car to be absolutely considered and not to be underestimated.
They are very useful to help the vehicle to be seen when driving in the fog but also in case of adverse weather conditions to signal its presence to other drivers, even with heavy rains.
When to Use Fog Lights
Fog lights are designed to be used when visibility is severely limited, mainly by fog, but also in other low visibility conditions such as snow or heavy rain. They are designed to make the car more visible, rather than helping to illuminate the road. In good visibility conditions, especially at night, they should not be used: this is what headlights are for. They should only be used when your car’s main lights are insufficient to make you visible to other drivers on the road.
When NOT to Use the Fog Lights
If the fog has cleared, you need to turn off the fog lights because you might dazzle other drivers on the road. Always be aware of the prevailing weather conditions: while the fog usually forms in the early morning, it will dissolve when the sun rises, so if you started the day with the fog lights on, be sure to continue evaluating the situation and turn them off when the weather is clear.
