Typically, driving lights are mounted above the front bumper about 14-30 inches from the
ground to provide extra high beam illumination. Driving lights can be mounted below the
bumper, although they will not be as efficient because the light will hit the ground sooner
and reduce the range of the light.
Visual aim is made with the center of the beam not spot 1.5 inches below the lamp center at
25 feet with the lamp facing straight forward (see below).
Do not use driving lights into oncoming traffic.
Driving lights should never be the only forward light source.
Driving lights should only be used with the headlamp high beams.
