Auxiliary Fog Lights
Auxiliary Fog Lights
PIAA Fog Kit
Typically, fog lights are mounted under the front bumper about 10 to 24 inches from the ground. There are two important issues to address when installing fog lights, the first is to minimize the amount of glare that returns to the driver's eyes, and the other is to minimize glare into oncoming drivers' eyes. Both must be accomplished while putting as much light as possible on the road.
These fog light aiming instructions are suggestions taken from common practice and the Society of Automotive Engineers (S.A.E.) standard J583. Some modifications to these instructions may be necessary to minimize glare.
Park the vehicle 25 feet from a wall on a level surface. Measure the distance between the center of the auxiliary light and the ground. Place a horizontal mark on the wall at that height.
Visual aim is made with the top of the fog light beam 4 inches below the lamp center at 25 feet with the lamp facing straight forward.
