Fog lights are made to disperse light low and wide. The closer to the road, the better. Yes, they will throw a beam of a sorts, so you can see the adjustment. I did mine by parking in front of my garage door, and adjust the lights to focus the same distance apart as the difference between the lights. As in, if there is 3 feet between the actual lights, there is 3 feet between the beam on the door. Fog lights will really only be seen well in the fog........Just sayin'lol. If you want to add more light at night, you'll need a set of passing lights or similar
