A type of light used on vehicles to illuminate the road in foggy conditions, helping drivers see better and be seen by others.
The driver turned on the foglight to navigate through the thick fog safely.
Foglight → It is formed from "fog" (from Old English *fogga*, meaning mist or vapor) and "light" (from Old English *leoht*, meaning illumination). The word "foglight" refers to a light designed to illuminate the road in foggy conditions.
Imagine a light that helps you see through the 'mist' ('fog') — that's why a foglight is used to illuminate the road in fog.
