1988-1998 Chevy Pickup Truck Fog Light with Bracket -Right Passenger

Fog lights are completely separate units from standard headlights. Fog lights have a unique beam shape. Their beams are flat and wide, and they are positioned low on the car, usually near the front bumper. The shape of the fog light beams usually resembles a narrow bar.

Fog lights are designed to illuminate a wide path of road with a relatively short distance. The proper mounting of fog lights are at a height of between 18” and 20” above the road. Fog forms about 20-24” above the road and stretches upward farther than we can see.  When fog lights are mounted properly, they project their light under the fog and forward down the road.  This helps you “see through” the fog, but of course there are limits.

They are meant to cut through the fog and light up the surface of the road so that drivers can see well enough to stay on the road and within their lane.
