How they work, and what you should expect from a fog light. To understand how fog lights work, we should first take a look at how fog works. Fog is a regular occurrence in many parts of the world, especially near large bodies of water.
Proper front fog lights are mounted low down on the bodywork, and are angled down at a steep. While many lighting systems are automatic, fog lights are a lighting element that you will most likely have to turn on yourself. Herbert Benson suggests inducing the bodys relaxation response. Fog lights work the same way as normal lights work. When the conditions are right, tiny water droplets or ice crystals can float in the air, just over the surface of the ground.
