Should I turn on fog lights or double flashing lights in foggy days?

Fog lights should be turned on. Visibility is very low because there is fog on foggy days. Fog lights have strong penetration, which can make drivers see the road more clearly, while double flashing lights have less penetration than fog lights.

When it rains, snows, fogs in winter or rains heavily in summer, as long as the visibility is less than 200m, the fog lights of the car must be turned on. The most important thing is to slow down, ensure traffic safety and remind yourself to keep a safe distance between the front and rear vehicles.

In some foggy or rainy weather, the road visibility is less than 100 meters. At this time, you need to turn on the fog lights and double flashing lights at the same time. Because the visibility is only 50 meters to 100 meters, it is not safe to turn on the fog lights. Only by turning on the double flashing and fog lights can we attract attention and ensure the driving safety of the front and rear vehicles and our own vehicles.

Double flashing lights are not specially designed like fog lights, and the light emitted is irregularly scattered like taillights, rather than irregularly radiated. Secondly, the brightness of double flashing lights is far less than that of fog lights.

At the same distance, the black car with fog lights is obviously more conspicuous than the white car with double flashing lights. Therefore, the light source and brightness of fog lamps are more suitable for low visibility weather than double flashing.
