How to Turn On Fog Lights? — BLIAUTO Unlocks the Key to Safer Driving

Driving in foggy or rainy weather significantly reduces visibility. Regular headlights often fail to penetrate thick fog, and that’s exactly where fog lights come in. However, many drivers are unfamiliar with how fog lights work and, more importantly, how to use them correctly. Today, BLIAUTO will guide you through how to properly turn on fog lights and what to keep in mind when using them.

1. What Are Fog Lights? Why Do You Need Them?

Fog lights are specialized automotive lamps designed for low-visibility environments. They are commonly found at both the front and rear of vehicles.

Front fog lights: Installed beneath the front bumper, they emit a wide, flat beam with strong penetration, illuminating the road immediately ahead.

Rear fog lights: Typically red and brighter than standard taillights, they make your vehicle more visible to drivers behind you.

In dense fog, heavy rain, or snow, fog lights greatly enhance safety and help prevent accidents.

2. Where Are Fog Lights and How Do You Operate Them?

1. Common Locations:

The location of the fog light switch varies by vehicle, but they are usually found in the following places:

Independent button: Usually located on the dashboard or to the left of the steering wheel, marked with a foggy beam icon.

Integrated with the headlight dial: Turning or pulling out the headlight dial activates the fog lights.

Combination switch: Some vehicles require turning on the low beam headlights first, then activating fog lights using a stalk-mounted switch.

2. Icon Identification:

Front fog light icon: A bulb symbol emitting three horizontal lines angled downward to the left, crossed by a wavy line (symbolizing fog penetration).

Rear fog light icon: Similar to the front fog light icon, but the lines angle to the right.

3. How to Operate:

For most vehicles, the standard procedure to turn on fog lights is as follows:

(1) Start the vehicle

Ensure the ignition is in the ON position or the engine is running.

(2) Turn on the low beam headlights

In many cars, the fog light switch only works when the low beams are on.

(3) Activate the front/rear fog lights

Press or rotate the fog light switch. A fog light icon will appear on the dashboard, indicating that the lights are on.

3. Important Fog Light Usage Tips

Do not misuse fog lights: Using them on clear nights or sunny days can produce glare, disturbing other drivers and may result in fines.

Use appropriately based on conditions: In heavy fog, both front and rear fog lights should be on. In light rain or mist, front fog lights alone may suffice.

Turn them off promptly: Once visibility improves, switch them off to prevent light pollution.

Check regularly: Especially rear fog lights, which can go unnoticed if they fail. Regular inspection is essential.

4. Smart Fog Lights in the Modern Age
