Fog Lights or Lamps: Who Needs Them?

The basic argument in favor of fog lamps is that regular headlights, and especially high beam headlights, tend to reflect back in a driver’s eyes. This type of dangerous situation can be avoided by aiming the lights at a steeper angle in a bar shape, which is what fog lamps are designed to do.

Further adding to the confusion is a misconception that all fog lights are yellow, and the fact that a lot of aftermarket suppliers use the terms “fog lamps” and “driving lamps” to refer to the exact same product or offer combined “fog and driving lamp” assemblies. The term “driving lamp” is actually a nebulous phrase that sometimes refers to main beam headlights, sometimes refers to auxiliary headlights used primarily for off-roading, and can even refer to products marketed for use in the fog.
