What is the difference between driving lights, spot lights, fog lights, and flood lights?

Driving Lights

Often referred to as fog lights, driving lights have a beam that is able to travel a longer distance, but not as wide.  Driving lights perform best when used to supplement your high-beams.  Or they may be aimed lower and supplement your low-beams.

Spot / Off-Road Lights

Spot lights are strictly for off-road usage due to their powerful, tight beam.  Using an array of spot lights will offer more coverage by aiming them at slightly different angles.

Fog Lights

Fog lights are generally mounted low on the vehicle such as the bumper or bumper grille.  The light pattern is very wide, with a flat horizontal cutoff.  When properly aimed, fog lights are the perfect complement to your low-beams.  This is by far the most popular beam pattern and are installed on many vehicles from the factory - though there's always room for improvement by upgrading your existing fog lights.

Flood Lights

Flood lights have a beam pattern that may be similar in width to a fog light, but the beam does not have a horizontal cutoff.  Therefore they are also for off-road use only.  As with spot lights, a mounting location high on the vehicle is ideal.
