Do you really need fog lights? Well, fog lights are only needed or effective in uncommon driving conditions. They are designed to cut down on the glare that is reflected back at you in bad weather. When there are suspended particles in the air from fog, snow, or dust normal headlights and high beams can cause blinding glare resulting in very poor visibility.
Fog lights are typically located in or below the front bumper of your vehicle. They are angled down to illuminate the ground directly in front of your vehicle. The goal is to provide illumination that will not reflect back into your eyes. What actually achieves this is the pattern of light that the fog light lenses produces.
Your normal headlights and especially your high beams create a blanket of light over a large area at a high enough angle to see far down the roadway. Fog lights create a distinct bar of light that illuminates down and to the sides. Good fog lights will have a sharp cutoff line on top that allows little light to show over it, preventing reflective glare from any particles above that.
Some think of fog lights as needing to be yellow light. There is evidence that the shorter blue and violet wavelengths of light can create a glare effect when reflecting off fog, snow or rain. So yellow light does have the advantage of being less likely to cause glare, but filtering out the blue light lowers the total light output of the lamp. So it is common for fog lamps to use white lighting.
