What Kind of Lighting Should You Use in Fog?｜BLIAUTO Professional Lighting Guide

Driving in heavy fog is both dangerous and highly challenging. Visibility drops significantly, making it difficult to judge road conditions, and even the slightest mistake can lead to serious accidents. In such conditions, the two most important safety needs are: seeing clearly and being seen clearly. Choosing the right lighting and using it correctly is absolutely essential.

So, what kind of lighting should you use when driving in foggy weather? BLIAUTO breaks it down for you.

1. Fog Lights Are Irreplaceable – Your First Choice

✅ Why Use Fog Lights?

Fog lights are specifically designed to deal with low-visibility conditions, especially in heavy fog, rain, or snow. Unlike headlights, fog lights are usually mounted lower on the vehicle and emit a wide, low beam that stays close to the road. This design helps penetrate the fog without excessive reflection, improving your visible range.

✅ Yellow Fog Lights vs. White Fog Lights

Yellow Fog Lights: Longer wavelength, better penetration, less likely to scatter in fog, more comfortable on the eyes, and better anti-glare performance.

White Fog Lights: More modern and brighter, but more prone to reflection in dense fog, which can create a “whiteout” effect.

BLIAUTO Recommendation: If you often drive in fog-prone areas, yellow LED fog lights are the most practical. If foggy days are rare, white lights can be a stylish yet functional option.

2. Be Cautious with Headlights – Never Use High Beams!

❌ Why Not Use High Beams?

Many drivers mistakenly believe “the brighter the better” when visibility is poor. But in fog, this is a dangerous misconception. High beams reflect off the water droplets in the fog, bouncing the light back and creating intense glare. This reduces your visibility and severely impacts oncoming drivers.

✅ What to Do Instead:

Turn off your high beams

Use a low beam + fog light combination

If your car has an automatic headlight system, manually switch to low beam to avoid accidental high beam use

3. Tail Lights and Rear Fog Lights – Make Sure You’re Seen

✅ The Role of Rear Fog Lights

Rear fog lights are much brighter than regular tail lights. Their purpose is to ensure that vehicles behind you can clearly see your position in the fog, helping to avoid rear-end collisions.

When to Use: Only when visibility is extremely poor — typically less than 100 meters.

⚠️ Caution: Rear fog lights are very bright. If you leave them on after the fog clears, they may dazzle drivers behind you. Turn them off as soon as visibility improves.
