There's a proper procedure for aiming them- Measure from the ground to the center of the lamp (let's say it's 18"). Then park 25 feet away from a wall on flat ground. Subtract 4" from your lamp height (so 14" for this example) and mark that on the wall with a long piece of tape. The top of your fog light cutoffs should aim for the tape.
Cover or unplug your headlights if you need to see it more clearly, and aim the fog lights one at a time.
These don't use stock "click wheel" adjusters. Basically what I did was tighten the mounting brackets to the lamps until I could barely move them. Then, after mounting them in the bumper, I could aim them from the outside by pushing them very hard up and down. Good luck!
