It’s expected that sometimes drivers don’t know the difference between headlights and fog lights. A simple definition is that our car’s headlights allow us to drive at night under usual driving conditions. On the other hand, fog lights help us in adverse weather and situations in which visibility is seriously reduced (to 100 meters or less)by fog, smoke, sand, or dust.
Fog lights are typically white or “selective yellow.” Selective yellow differs from the amber or orange light on turn signals. It is a paler yellow that dazzles less by eliminating the “blue” of white light.
Yellow fog lights became famous for their effectiveness in dispersing the water particles that form the fog, allowing you to see better, and because they look fantastic.
For a brief period in the early-2000s, yellow fog lights were all the rage. But between lighting regulations in most countries requiring all headlights to produce white light and technological advances in modern headlights, yellow fog lights seem to be phased out in recent years. But it’s time to bring them back!
The Subaru WRX’s rally heritage really comes alive when you see it rocking a pair of yellow fog lights in the snow.
