What is the best light type (meaning fog, flood, driving, or long range) for the following different mounting positions.

1. Front bumper mount with factory fog lights?
2. Windshield hinge mount?
3. Roof top light bar mount forward facing?
4. Rear bumper mount?

I'm sure that the type of terrain has a lot to do with it, so looking for opinions to different conditions too.

 

1. Driving
2. Spot/Long Range
3. Either Spot or Driving. If running 4 lights usually a pair of riving lights on the outside and a pair of spots on the inside locations.
4. Flood
