Fog lights, or fog lamps, are found on the front of vehicles and they help drivers navigate during inclement weather; specifically foggy, rainy or snowy weather where the color of the sky is more gray than either dark or light. Fog lights are mounted in such a way that they provide additional lighting directly onto the road in front of you and are colored in such a way that they offer a little additional visibility of the road.

When driving in inclement weather or poor visibility conditions, standard automotive headlights can cause blinding as they are focused straight ahead of you. When it is snowing or raining hard or foggy, “straight in front of you” is not necessarily what you need to see – hence the value of the fog lights to create a swath of light right at your nearest path.

What to know about fog lights:

  • Fog lights are different than driving lights, in that fog light assemblies generally create a yellow light through the lightly-colored lenses. Driving lights generally are white, but this is not always the case and it tends to vary by manufacturer.

  • These low-hanging lights are subject to the very worst of road conditions – every puddle that you drive through, all the road debris such as small rocks and tree pieces – these are all coming directly at your fog lights so they have to be incredibly sturdy. Apart from being broken, fog lights also tend to get scratched quite easily, which can significantly dim their performance over time.

  • Provide you with higher visibility under adverse weather conditions

  • Be free of scratches and damage (if you purchase remanufactured lights)

  • Have their original shade of yellow or amber, in order to aid visibility under those tough conditions
