What light should I turn on when driving in a rainstorm?

In this weather, turn on the low beam and the front and rear fog lights.

When the visibility of rainstorm is low, you can turn on the low beam and the front and rear fog lights.

If the visibility of driving in heavy rain has little effect, you can directly turn on the low beam of the vehicle. If the visibility is low due to heavy rain, turn on the fog lights, because the fog lights are very penetrating, which can let other traffic participants notice the existence of your vehicle through the lights and increase driving safety.
