Which Lights to Use When Driving in the Rain?

[Joan]

When the rain is light, you should use the width indicator lights. When the rain is heavy, you should turn on the headlights or front fog lights, and avoid using hazard lights while driving. Also, do not use the side marker lights for extended periods. Below are the lights to use in different scenarios: 1. Use width indicator lights when the rain is light: The use of lights when driving in the rain is very particular. At the beginning of the rain, the sky is relatively dark, but visibility is still decent. In this case, you should use the width indicator lights. 2. Turn on the headlights or front fog lights when the rain is heavy: When the rain is heavier, the rainwater itself will obstruct your vision. Additionally, water on the road will be splashed up by the rolling tires of the vehicle in front, creating a mist that can significantly affect visibility. In this situation, you should turn on the headlights or front fog lights. 3. Use rear fog lights during heavy rain: Rear fog lights should only be used when the rain is extremely heavy because the red taillights already have excellent penetration power, and ordinary heavy rain usually doesn’t block their light. Rear fog lights are very bright and are designed to penetrate thick fog.
