Ideally, fog lights should emit a selective yellow or white light. Selective yellow light, with its longer wavelength, is particularly effective in scattering through fog, rain, and snow. This allows for better visibility compared to white light in such conditions. White light, however, is more versatile and generally preferred for clear weather driving due to its better illumination of the road surface.
Understanding Fog Light Colors
Why Selective Yellow?
Selective yellow light has been proven to reduce the “backscatter” effect, which is the reflection of light back towards the driver by fog particles. This backscatter can create a blinding glare, reducing visibility even further. Selective yellow light minimizes this effect, improving visibility and safety in foggy conditions.
The Case for White
White light, while less effective in dense fog, provides a broader spectrum of visibility in clear weather. Modern LED and halogen fog lights offer excellent white light output, making them a popular choice for drivers who prioritize a single, all-purpose fog light solution.

Legal Regulations Regarding Fog Light Color
In many regions, regulations dictate that fog lights must be either white or selective yellow. Using other colors, such as blue or green, is often illegal and can result in fines. These regulations are in place to ensure road safety and prevent confusion among drivers. It’s important to consult local laws to ensure compliance. Choosing the correct fog light color is not only about performance but also about adhering to legal requirements.
Checking Local Laws
It’s crucial to familiarize yourself with the specific fog light color regulations in your area. These regulations can vary, and some areas may have stricter rules than others. Checking your local Department of Motor Vehicles (DMV) website or contacting a local law enforcement agency can provide clarity on the legal requirements for fog light colors.

Choosing the Right Fog Lights
Factors to Consider
When choosing fog lights, consider the prevailing weather conditions in your area. If you frequently encounter fog, snow, or heavy rain, selective yellow fog lights are the recommended choice. For areas with generally clear weather, white fog lights offer a versatile solution.
Installation and Adjustment
Proper installation and adjustment are critical for optimal fog light performance. Fog lights should be aimed low and slightly outwards to illuminate the road surface directly in front of the vehicle. Incorrectly aimed fog lights can blind oncoming drivers and reduce visibility.
