Front fog lights are definitely not standard equipment and there is a lot of confusion about how and when to use them. Unlike high and low beam, both of which are used regularly, fog lights are only really useful in a handful of very specific situations. The fact is that fog lights are specifically designed for use in bad weather and other situations where visibility is severely limited by fog, mist or even sand and dust in the air.
How to Use Fog Lights – Car Fog Lights Explained
The basic argument in favor of fog lights is that regular headlights, especially high beam headlights, tend to bounce back into 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 lights are designed for.
Further adding to the confusion is the misconception that all fog lights are yellow and the fact that many aftermarket suppliers use the terms “fog lights” and “driving lights” to refer to the exact same product or offer combined “fog and driving light” assemblies. The term “driving light” is actually a vague term that sometimes refers to high beams, sometimes to auxiliary headlamps used primarily for off-road driving, and can even refer to products marketed for use in fog.
Forward-facing fog lamps and fog lights are a type of automotive headlight designed to emit light in a bar-shaped beam. The beam is typically designed to have a sharp cutoff at the top, and the actual lights are typically mounted low and aimed at a sharp angle toward the ground.
