driving lights vs fog lights

[northerngmc]

I am looking at installing extra lights on my front bumper of my 2004 2500HD and am looking for some information on driving lights vs fog lights.

I am not looking at yellow fog lights but clear lights and I am more concerned about the spray pattern of light.

The attached diagram shows the difference between the spray pattern of the lights.

I am looking for lights that will light up the area in front of me while driving on quiet, untravelled roads, and I have concerns about animals (Bears, bison, moose, dear and ?) in the ditch.

I like the driving lights for the distance but I am afraid that they will not light up the ditches and show me animals.

Any experience here as to how much difference there is in the distance between the two types of lights?

Also how many watts should I be looking for? THe lights I am looking at are Piaa 510's.
