Driving lights work with your hi-beams for greater visibility at longer distances. They project a long, narrow beam of light in a variety of patterns which greatly extend your range of view.
Fog lights work together with your low-beams to improve your visibility in foul weather, such as fog, rain, snow and mist. They emit a low, wide pattern of light that's designed to shine below the haze. This reduces the amount of blinding glare that occurs when you turn on your hi-beams in foggy weather.
