Fog lights serve two purposes in life these days. Historically they have been used as intended and as their name conveys, under foggy conditions. Fog lights are mounted low to the ground, below one’s headlights, and have a sharp cut-off. Much like your low-beam doesn’t shine higher than a certain point, fog lights are designed with a similar restriction built-in. The reason for this is to prevent the fog right in front of you from being illuminated, causing glare, and effectively blinding you. Instead, they shine a wide beam, usually brighter than a low beam, close to the ground. They are designed for low-speed driving, to illuminate the ground and edges when you otherwise can’t see. It’s rare for us to encounter such conditions in our day-to-day life, but that hasn’t curbed the demand for cars to install fog lights. The second purpose, and many people’s main reason, for having fog lights installed, is that they look cool. While some jurisdictions have outlawed the use of fog lights in conditions that don’t warrant them, it doesn’t stop many people from driving around with them on, a day-to-day basis. And while we don’t condone this use, a decent set of fog lights does make a good-looking car that much more appealing. If you’re involved in the car-modding scene, then, by all means, have your fog lights on during meet-ups, but not on the road.
