Ever found yourself squinting through thick fog or struggling to see during a heavy rainstorm? Driving in low visibility can be stressful, but the right lighting makes all the difference. If you’ve ever wondered what fog lights are or how to turn them on, you’re in the right place! Let’s break down when and how to use them so you can stay ready on the road.

What Are Fog Lights?

Fog lights are specialized lamps designed to improve visibility in fog, dust, or heavy rain. Unlike regular headlights, which sit higher on the vehicle and project a long-range beam, fog lights are mounted lower on the front bumper. This positioning helps them shine a short, wide beam under the fog to reduce glare and give you a clearer view of the road.

Do All Cars Have Fog Lights?

Not necessarily. While many modern cars come equipped with fog lights, they’re not a legal requirement in the U.S. Some vehicles, particularly higher trims and SUVs, include them as standard, while others may not have them at all.

To check if your car has fog lights, look near the lower front bumper or check your dashboard for the fog light symbol—a half-oval with a wavy line and dashes. Some vehicles even have rear fog lights, which help other drivers see you in poor conditions. If your car doesn’t have fog lights but you frequently drive in foggy or dusty areas, installing them can be a smart investment.

How to Turn On Fog Lights

Not sure how to activate your fog lights? Here’s what to do:

1. Turn on your headlights: Fog lights won’t work unless your regular headlights are on.
2. Find the fog light control: Look for a button or dial near your headlight controls. The fog light symbol will help you identify it.
   • Front fog lights: The symbol’s half-oval is on the right side of the vertical line.
   • Rear fog lights: The half-oval is on the left side of the vertical line.
3. Activate the fog lights: If your control is a dial, rotate it. If it’s a button, press it.
4. Look for the dashboard indicator: A green or amber light on your dashboard confirms they’re on.

What Lights Should You Use in Fog and Other Conditions?

Knowing when to use fog lights (and when not to) is key. Here’s what you need to know:

Foggy Conditions

You might think high beams would help in fog, but they actually do the opposite and reflect light off water droplets, making visibility worse. Instead, use fog lights to cut through the mist and illuminate the road directly ahead.

Dusty Conditions

Fog lights can be helpful in light dust storms, just like in fog. However, in a severe dust storm, it is better to pull over, turn off your lights, and wait it out. This prevents other drivers from mistaking your lights for a clear path and unintentionally crashing into you.

Rain or Snow

Fog lights can help increase visibility in light rain or snow. But in heavy rain or snow, they might reflect off wet roads and blind other drivers. In those cases, low-beam headlights are the better choice.

Dark Roads

If it’s dark but clear, use your regular headlights, not fog lights. High beams work well on unlit roads but should be switched off when other cars are nearby to avoid blinding other drivers.
