Fog Lights - A Boon in the Foggy Weather Condition

Posted by on

Fog lights are now a safety features in every car because they are necessary in poor visibility conditions due to like rain, fog, dust or snow. They are designed specifically to be used at low speed to add to the illumination directed to the surface and verges of the roads. Often so, people confuse the purpose of front fog lamps and driving lamps. This is because of the myth that fog lamps are supposed to be selective yellow light, and that any other auxiliary lamp which is white is presumed to be a driving light.

The two are used interchangeably by drivers without knowing the purpose of each. A study in the US showed that more drivers use these lights during dry weather than use them in poor weather. Sometimes they are used instead of dipped-beam headlamps to reduce the glare back coming from fog or falling snow. Use of front fog lamps minus the low beam headlamps depends on the local legal guidelines. The purpose of the fog lamp is to show the driver the road edges, lane markings and the foreground abruptly appearing during road drive.  When used with headlamps in extremely poor visibility, a driver can maneuver safely at slow speed in snow, fog or heavy rains.

To understand what fog is, it is a regular occurrence anywhere, especially near large bodies of water. When the conditions are right, tiny water droplets or ice crystals can float in the air, just over the surface of the ground. They form a cloud and block your visibility. These tiny water droplets or ice crystals decrease your visibility even further by reflecting any light that hits them. This way, your own high beams are reflected back into your eyes disturbing visibility and making driving risky.

Fog lamps take a different approach to all that water vapor hanging over the road. They work in multiple poor visibility conditions, including fog, mist, snow, and even blowing sand. In order to enable you to see the road through the fog, factory-equipped fog lamps are placed as low as reasonably possible, usually in the lower bumper cover on most modern vehicles. Despite its appearance, fog typically doesn't touch the ground but hovers about 18 inches over the surface. The low placement lets the light beam hit the road without interference.

With a sharp cutoff angle in the top of the light housing, none of the beam shines up to reflect off the fog, only illuminating the road ahead. Angled downward, fog lights do not have the same reach as your headlamps, but they give out the right kind of light, enough to see the road ahead for drivers. They are a great help to slowly negotiate the stretch of poor visibility. Since the fog lights aren't just reflecting light back, oncoming drivers get an indication of your presence on the road, the second safety benefit.

 If your car isn’t equipped with factory fitted fog lamps, it's easy and affordable to upgrade. There are available DIY kits specific to whichever is your make of vehicle. SELIGHT fog lights are an affordable make in LED fog lamps, and can be added to just about any vehicle. Just select the style and size that you prefer and find space to mount them where they won't be damaged.
