The bottom adjusting screw on the fog lamp allows you to perform any required modifications.
Q: How to properly aim front fog lights for road illumination and safety on Cadillac Eldorado?
A: For correct road illumination install your vehicle 7.6 meters (25 feet) from a flat surface then set it on a level ground to aim your fog lamps.
